SIMD accelerated URL decoding.
It converts a string such as Hello+brave%20world%21 to Hello brave world!.
Right now there is SIMD support for SSE4.1 instructions. In the future there may be AVX2 and AVX-512 implementations. There is also a fallback in standard Rust in case the binary is not compiled with support for SSE4.1.
The API and features are not stable.
Opportunities for improvement include:
- runtime CPU detection
- allow tests to run even if current system does not support all CPU instructions (eg qemu)
- AVX2 support
- AVX-512 support
- instructions for ARM
