"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

|
||||
copyright license to reproduce, prepare Derivative Works of,

|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You

or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You

(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||

Rust Quasi-Quoting
|

|
||||
|
||||
This crate provides the [`quote!`] macro for turning Rust syntax tree data
|
||||
structures into tokens of source code.
|
||||
|
||||
[`quote!`]: https://docs.rs/quote/1.0/quote/macro.quote.html
|
||||
|
||||
Procedural macros in Rust receive a stream of tokens as input, execute arbitrary
|
||||
Rust code to determine how to manipulate those tokens, and produce a stream of
|
||||
tokens to hand back to the compiler to compile into the caller's crate.
|
||||
Quasi-quoting is a solution to one piece of that — producing tokens to
|
||||
return to the compiler.
|
||||
|
||||
The idea of quasi-quoting is that we write *code* that we treat as *data*.
|
||||
Within the `quote!` macro, we can write what looks like code to our text editor
|
||||
or IDE. We get all the benefits of the editor's brace matching, syntax
|
||||
highlighting, indentation, and maybe autocompletion. But rather than compiling
|
||||
that as code into the current crate, we can treat it as data, pass it around,
|
||||
mutate it, and eventually hand it back to the compiler as tokens to compile into
|
||||
the macro caller's crate.
|
||||
|
||||
This crate is motivated by the procedural macro use case, but is a
|
||||
general-purpose Rust quasi-quoting library and is not specific to procedural
|
||||
macros.
|
||||
|
||||
```toml
|
||||
[dependencies]
|
||||
quote = "1.0"
|
||||
```
|
||||
|
||||
*Version requirement: Quote supports rustc 1.56 and up.*<br>
|
||||
[*Release notes*](https://github.com/dtolnay/quote/releases)
|
||||
|
||||
<br>
|
||||
|
||||
## Syntax
|
||||
|
||||
The quote crate provides a [`quote!`] macro within which you can write Rust code
|
||||
that gets packaged into a [`TokenStream`] and can be treated as data. You should
|
||||
think of `TokenStream` as representing a fragment of Rust source code.
|
||||
|
||||
[`TokenStream`]: https://docs.rs/proc-macro2/1.0/proc_macro2/struct.TokenStream.html
|
||||
|
||||
Within the `quote!` macro, interpolation is done with `#var`. Any type
|
||||
implementing the [`quote::ToTokens`] trait can be interpolated. This includes
|
||||
most Rust primitive types as well as most of the syntax tree types from [`syn`].
|
||||
|
||||
[`quote::ToTokens`]: https://docs.rs/quote/1.0/quote/trait.ToTokens.html
|
||||
[`syn`]: https://github.com/dtolnay/syn
|
||||
|
||||
```rust
|
||||
let tokens = quote! {
|
||||
struct SerializeWith #generics #where_clause {
|
||||
value: &'a #field_ty,
|
||||
phantom: core::marker::PhantomData<#item_ty>,
|
||||
}
|
||||
|
||||

## Repetition
|
||||
|
||||
Repetition is done using `#(...)*` or `#(...),*` similar to `macro_rules!`. This
|
||||
iterates through the elements of any variable interpolated within the repetition
|
||||
and inserts a copy of the repetition body for each one. The variables in an
|
||||
interpolation may be anything that implements `IntoIterator`, including `Vec` or
|
||||
a pre-existing iterator.
|
||||
|
||||
- `#(#var)*` — no separators
|
||||
- `#(#var),*` — the character before the asterisk is used as a separator
|
||||
- `#( struct #var; )*` — the repetition can contain other things
|
||||
- `#( #k => println!("{}", #v), )*` — even multiple interpolations
|
||||
|
||||
Note that there is a difference between `#(#var ,)*` and `#(#var),*`—the latter
|
||||
does not produce a trailing comma. This matches the behavior of delimiters in
|
||||
`macro_rules!`.
|
||||
|
||||
<br>
|
||||
|
||||
## Returning tokens to the compiler
|
||||
|
||||
The `quote!` macro evaluates to an expression of type
|
||||
`proc_macro2::TokenStream`. Meanwhile Rust procedural macros are expected to
|
||||
return the type `proc_macro::TokenStream`.
|
||||
|
||||
The difference between the two types is that `proc_macro` types are entirely
|
||||
specific to procedural macros and cannot ever exist in code outside of a
|
||||
procedural macro, while `proc_macro2` types may exist anywhere including tests
|
||||
and non-macro code like main.rs and build.rs. This is why even the procedural
|
||||
macro ecosystem is largely built around `proc_macro2`, because that ensures the
|
||||
libraries are unit testable and accessible in non-macro contexts.
|
||||
|
||||
There is a [`From`]-conversion in both directions so returning the output of
|
||||
`quote!` from a procedural macro usually looks like `tokens.into()` or
|
||||
`proc_macro::TokenStream::from(tokens)`.
|
||||
|
||||
[`From`]: https://doc.rust-lang.org/std/convert/trait.From.html
|
||||
|
||||
<br>
|
||||
|
||||
## Examples
|
||||
|
||||
### Combining quoted fragments
|
||||
|
||||
Usually you don't end up constructing an entire final `TokenStream` in one
|
||||
piece. Different parts may come from different helper functions. The tokens
|
||||
produced by `quote!` themselves implement `ToTokens` and so can be interpolated
|
||||
into later `quote!` invocations to build up a final result.
|
||||
|
||||
```rust
|
||||
let type_definition = quote! {...};
|
||||
let methods = quote! {...};
|
||||
|
||||
let tokens = quote! {
|
||||
#type_definition
|
||||
#methods
|
||||
};
|
||||
```
|
||||
|
||||
### Constructing identifiers
|
||||
|
||||
Suppose we have an identifier `ident` which came from somewhere in a macro
|
||||
input and we need to modify it in some way for the macro output. Let's consider
|
||||
prepending the identifier with an underscore.
|
||||
|
||||
Simply interpolating the identifier next to an underscore will not have the
|
||||
behavior of concatenating them. The underscore and the identifier will continue
|
||||
to be two separate tokens as if you had written `_ x`.
|
||||
|
||||
```rust
|
||||
// incorrect
|
||||
quote! {
|
||||
let mut _#ident = 0;
|
||||
}
|
||||
```
|
||||
|
||||
The solution is to build a new identifier token with the correct value. As this
|
||||
is such a common case, the `format_ident!` macro provides a convenient utility
|
||||
for doing so correctly.
|
||||
|
||||
```rust
|
||||
let varname = format_ident!("_{}", ident);
|
||||
quote! {
|
||||
let mut #varname = 0;
|
||||
}
|
||||
```
|
||||
|
||||
Alternatively, the APIs provided by Syn and proc-macro2 can be used to directly
|
||||
build the identifier. This is roughly equivalent to the above, but will not
|
||||
handle `ident` being a raw identifier.
|
||||
|
||||
```rust
|
||||
let concatenated = format!("_{}", ident);
|
||||
let varname = syn::Ident::new(&concatenated, ident.span());
|
||||
quote! {
|
||||
let mut #varname = 0;
|
||||
}
|
||||
```
|
||||
|
||||
### Making method calls
|
||||
|
||||
Let's say our macro requires some type specified in the macro input to have a
|
||||
constructor called `new`. We have the type in a variable called `field_type` of
|
||||
type `syn::Type` and want to invoke the constructor.
|
||||
|
||||
```rust
|
||||
// incorrect
|
||||
quote! {
|
||||
let value = #field_type::new();
|
||||
}
|
||||
```
|
||||
|
||||
This works only sometimes. If `field_type` is `String`, the expanded code
|
||||
contains `String::new()` which is fine. But if `field_type` is something like
|
||||
`Vec<i32>` then the expanded code is `Vec<i32>::new()` which is invalid syntax.
|
||||
Ordinarily in handwritten Rust we would write `Vec::<i32>::new()` but for macros
|
||||
often the following is more convenient.
|
||||
|
||||
```rust
|
||||
quote! {
|
||||
let value = <#field_type>::new();
|
||||
}
|
||||
```
|
||||
|
||||
This expands to `<Vec<i32>>::new()` which behaves correctly.
|
||||
|
||||
A similar pattern is appropriate for trait methods.
|
||||
|
||||
```rust
|
||||
quote! {
|
||||
let value = <#field_type as core::default::Default>::default();
|
||||
}
|
||||
```
|
||||
|
||||
<br>
|
||||
|
||||
## Hygiene
|
||||
|
||||
Any interpolated tokens preserve the `Span` information provided by their
|
||||
`ToTokens` implementation. Tokens that originate within a `quote!` invocation
|
||||
are spanned with [`Span::call_site()`].
|
||||
|
||||
[`Span::call_site()`]: https://docs.rs/proc-macro2/1.0/proc_macro2/struct.Span.html#method.call_site
|
||||
|
||||
A different span can be provided explicitly through the [`quote_spanned!`]
|
||||
macro.
|
||||
|
||||
[`quote_spanned!`]: https://docs.rs/quote/1.0/quote/macro.quote_spanned.html
|
||||
|
||||
<br>
|
||||
|
||||
## Non-macro code generators
|
||||
|
||||
When using `quote` in a build.rs or main.rs and writing the output out to a
|
||||
file, consider having the code generator pass the tokens through [prettyplease]
|
||||
before writing. This way if an error occurs in the generated code it is
|
||||
convenient for a human to read and debug.
|
||||
|
||||
Be aware that no kind of hygiene or span information is retained when tokens are
|
||||
written to a file; the conversion from tokens to source code is lossy.
|
||||
|
||||
Example usage in build.rs:
|
||||
|
||||
```rust
|
||||
let output = quote! { ... };
|
||||
let syntax_tree = syn::parse2(output).unwrap();
|
||||
let formatted = prettyplease::unparse(&syntax_tree);
|
||||
|
||||
let out_dir = env::var_os("OUT_DIR").unwrap();
|
||||
let dest_path = Path::new(&out_dir).join("out.rs");
|
||||
fs::write(dest_path, formatted).unwrap();
|
||||
```
