Crate httparse

httparse

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.
