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](https://qoiformat.org/qoi-specification.pdf).
- Zero unsafe code.
- Supports decoding from / encoding to `std::io` streams directly.
- Roundtrip-tested vs the reference C implementation; fuzz-tested.
### Examples
```rust
todo!();
```
