It is distributed under the same licenses: MIT and\nUNLICENSE.\n\nIn my limited tests, the fallback version ranges from about equal to 5.5x faster\nthan FreeBSD's stock `memchr()` (a simple bytewise loop) on amd64.\n\nOn i386 it's about 2.6x slower; 1.7x slower if `uintptr_t` is replaced with\n`uint64_t`.\n\nThe SSE2 version is about 2.5-13x faster.\n\n\n[rust-memchr]: https://github.com/BurntSushi/rust-memchr\n[original]: https://github.com/BurntSushi/rust-memchr/blob/b0a29f267f4a7fad8ffcc8fe8377a06498202883/src/fallback.rs#L45-L81\n[sse2]: https://github.com/BurntSushi/rust-memchr/blob/b0a29f267f4a7fad8ffcc8fe8377a06498202883/src/x86/sse2.rs#L18-L187\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffreaky%2Ffast-memchr","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffreaky%2Ffast-memchr","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffreaky%2Ffast-memchr/lists"}
