- Implement Clone for PRNGs
|
|
|
|

|
|
runtime is removed from Rust).
|
|
|
|
### Fixed
|
|

|
|

|
|

|
|
- Removed the Deprecated `choose_option`
|
|
|
|
|
|
## [Rust 0.11.0] - 2014-07-02
|
|
### Added
|
|
- document when to use `OSRng` in cryptographic context, and explain why we use `/dev/urandom` instead of `/dev/random`
|
|
- `Rng::gen_iter()` which will return an infinite stream of random values
|
|
- `Rng::gen_ascii_chars()` which will return an infinite stream of random ascii characters
|
|
|
|
### Changed
|
|
- Now only depends on libcore! 2adf5363f88ffe06f6d2ea5c338d1b186d47f4a1
|
|
- Remove `Rng.choose()`, rename `Rng.choose_option()` to `.choose()`
|
|
- Rename OSRng to OsRng
|
|
- The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`,
|
|
but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice
|
|
structure now has a lifetime associated with it.
|
|
- The `sample` method on `Rng` has been moved to a top-level function in the
|
|
`rand` module due to its dependence on `Vec`.
|
|
|
|
### Removed
|
|
- `Rng::gen_vec()` was removed. Previous behavior can be regained with
|
|
`rng.gen_iter().take(n).collect()`
|
|
- `Rng::gen_ascii_str()` was removed. Previous behavior can be regained with
|
|
`rng.gen_ascii_chars().take(n).collect()`
|
|
- {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all
|
|
relied on being able to use an OSRng for seeding, but this is no longer
|
|
available in librand (where these types are defined). To retain the same
|
|
functionality, these types now implement the `Rand` trait so they can be
|
|
generated with a random seed from another random number generator. This allows
|
|
the stdlib to use an OSRng to create seeded instances of these RNGs.
|
|
- Rand implementations for `Box<T>` and `@T` were removed. These seemed to be
|
|
pretty rare in the codebase, and it allows for librand to not depend on
|
|
liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not
|
|
supported.
|
|
- Remove a slew of old deprecated functions
|
|
|
|
|
|
## [Rust 0.10] - 2014-04-03
|
|
### Changed
|
|
- replace `Rng.shuffle's` functionality with `.shuffle_mut`
|
|
- bubble up IO errors when creating an OSRng
|
|
|
|
### Fixed
|
|
- Use `fill()` instead of `read()`
|
|
- Rewrite OsRng in Rust for windows
|
|
|
|
## [0.10-pre] - 2014-03-02
|
|
### Added
|
|
- Seperate `rand` out of the standard library
|
|
|
