Quick summary:

- One of the [fastest](https://github.com/aldanor/qoi-fast#benchmarks)
  QOI encoders/decoders out there.
- Compliant with the latest QOI [format specification]().
- Zero unsafe code.
- Supports decoding from / encoding to `std::io` streams directly.
- Roundtrip-tested vs the reference C implementation; fuzz-tested.

### Examples

```rust
todo!();
```
