This crate contains a basic port of <https://github.com/jk-jeon/dragonbox> to
Rust for benchmarking purposes.

Please see the upstream repo for an explanation of the approach and comparison
to the Ryū algorithm.

## Example

```rust
fn main() {
    let mut buffer = dragonbox::Buffer::new();
    let printed = buffer.format(1.234);
    assert_eq!(printed, "1.234E0");
}
```
