| //! |
| //! A push library for parsing HTTP/1.x requests and responses. |
| //! |
| //! The focus is on speed and safety. Unsafe code is used to keep parsing fast, |
| //! but unsafety is contained in a submodule, with invariants enforced. The |
| //! parsing internals use an `Iterator` instead of direct indexing, while |
| //! skipping bounds checks. |
| //! |
| //! With Rust 1.27.0 or later, support for SIMD is enabled automatically. |
| //! If building an executable to be run on multiple platforms, and thus |
| //! not passing `target_feature` or `target_cpu` flags to the compiler, |
| //! runtime detection can still detect SSE4.2 or AVX2 support to provide |
| //! massive wins. |
| //! |
| //! If compiling for a specific target, remembering to include |
| //! `-C target_cpu=native` allows the detection to become compile time checks, |
| //! making it *even* faster. |
