Rust utilities for YUV format handling and conversion.

Fast and simple YUV approximation conversion in pure Rust. At most the same as libyuv does. Performance will be equal to libyuv or slightly higher on platforms where SIMD is implemented. Otherwise equal or slower.

Mostly implemented AVX-512, AVX2, SSE, NEON, WASM

X86 targets with SSE and AVX uses runtime dispatch to detect available cpu features.

Supports:

• YCbCr ( aka YUV )
• YCgCo
• YCgCo-R
• YUY2
• Identity ( GBR )
• Sharp YUV

All the methods support RGB, BGR, BGRA and RGBA

SIMD

rustc avx2, avx512f, avx512bw, neon, sse4.1 features should be set when you expect than code will run on supported device.

For AVX-512 target feature avx512bw is required along with feature nightly_avx512 and nightly rust channel compiler.

Wasm simd128 should be enabled for implemented SIMD wasm paths support
