HttpMuncher: Rust Streaming HTTP parser

Rust wrapper for NodeJS http-parser library.

It's intended to be used as an HTTP/1.x protocol handler in Rust-based web servers.

Motivation

Why not write a brand new HTTP parser from scratch in Rust or just use an existing crate such as httparse?

Here's why:

• NodeJS HTTP parser library is based on a full-featured and robust nginx's HTTP parser, and it's safe, fast, and lightweight by design;
• It's compatible with HTTP/1.1, including upgrade connections and chunked responses;
• I haven't found a decent HTTP parser that is capable of streamed parsing, i.e. the one that can eagerly use partial data that comes from a TCP socket;
• Rust's FFI has little to no overhead;
• In most cases, it's silly to reinvent the wheel;
• It was a lot of fun trying to learn Rust along the way. :)

Usage

Add the library to your Cargo.toml dependencies section:

[dependencies]
http-muncher = "0.3"

Or, for the edge version:

[dependencies]
http-muncher = {git = "https://github.com/nbaksalyar/rust-streaming-http-parser"}

You can find usage example in examples/parser.rs (run it by executing cargo run --example parser) and in the library tests.

API documentation

You can find API docs here.

Alternative libraries

• http-parser-rs - Rust port of NodeJS HTTP parser (without FFI usage).
• httparse - pure Rust HTTP parser implementation.
