qoi-fast

Fast encoder/decoder for QOI image format, implemented in pure and safe Rust.

Quick summary:

One of the fastest QOI encoders/decoders out there.
Compliant with the latest QOI format specification.
Zero unsafe code.
Supports decoding from / encoding to std::io streams directly.
no_std support.
Roundtrip-tested vs the reference C implementation; fuzz-tested.

Examples
