This crate provides a fast conversion of integer primitives to decimal strings.
|
||
|
|
The implementation comes straight from [libcore] but avoids the performance
|
||
|
|
penalty of going through [`core::fmt::Formatter`].
|
||
|
|
|
||
|
|
See also [`ryu`] for printing floating point primitives.
|
||
|
|
|
||
|
|
*Version requirement: rustc 1.36+*

## Example
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn main() {
|
||
|
|
let mut buffer = itoa::Buffer::new();
|
||
|
|
let printed = buffer.format(128u64);
|
||
|
|
assert_eq!(printed, "128");
|
||
|
|
}
|
||
|
|
```
