# UTF-8 decode

<!-- cargo-rdme start -->
This crates provides incremental UTF-8 decoders implementing the
[`Iterator`] trait, wrapping around [`u8`] bytes iterators.
It also provide the `const`-compatible [`try_decode_char`] to decode UTF-8
byte streams, even in `const` contexts.
[`u8`]: std::primitive::u8
[`Iterator`]: std::iter::Iterator
[`try_decode_char`]: https://docs.rs/utf8-decode/latest/utf8_decode/fn.try_decode_char.html
### `Decoder`
The [`Decoder`] iterator can be used, for instance, to decode `u8` slices.
```rust
use utf8_decode::Decoder;
let bytes = [72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33];
let decoder = Decoder::new(bytes.iter().cloned());
let mut string = String::new();
for c in decoder {
string.push(c?);
}
println!("{}", string);
```
### `TryDecoder`
The [`TryDecoder`] iterator can be used, for instance, to decode UTF-8
encoded files.
```rust
use utf8_decode::TryDecoder;
let file = File::open("examples/file.txt")?;
let decoder = TryDecoder::new(file.bytes());
let mut string = String::new();
for c in decoder {
string.push(c?);
}
```
