|
|
|
- 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.
