An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.

// Macros for use in writing tests generic over &str/&[u8].
macro_rules! text { ($text:expr) => { $text } }
macro_rules! t { ($text:expr) => { text!($text) } }

macro_rules! bytes { ($text:expr) => { $text.as_bytes() } }
macro_rules! b { ($text:expr) => { bytes!($text) } }

// N.B. The expansion API for &str and &[u8] APIs differs slightly for now,
// but they should be unified in 1.0. Then we can move this macro back into
// tests/api.rs where it is used. ---AG
