# async-utf8-decoder
## Asynchronous and incremental UTF-8 decoder
`async-utf8-decoder` crate provides `Utf8Decoder` which allows to convert any object which
implements `AsyncRead` trait into a string stream which implements `Stream` trait.
### Example
```rust
use futures::io;
use futures::channel::mpsc;
use async_utf8_decoder::Utf8Decoder;
let (mut tx, rx) = mpsc::unbounded::<io::Result<Vec<u8>>>();
let mut decoder = Utf8Decoder::new(rx.into_async_read());
tx.send(Ok(vec![240])).await?;
assert!(timeout(decoder.next()).await.is_err());
tx.send(Ok(vec![159])).await?;
assert!(timeout(decoder.next()).await.is_err());
tx.send(Ok(vec![146])).await?;
assert!(timeout(decoder.next()).await.is_err());
tx.send(Ok(vec![150])).await?;
assert_eq!("💖", timeout(decoder.next()).await?.unwrap()?);
assert!(timeout(decoder.next()).await.is_err());
```
