README
fast-strip-ansi
A performance-optimized ANSI escape sequence stripper.
Full VT-100/ANSI support.
No startup cost for regex compilation.
Usage
let input = b"Hello, world!\x1b[31mHello, world!\x1b[0m";
let output = strip_ansi_string(input);
Security and Correctness
fast-strip-ansi is correct and secure. It contains a true VT-100/ANSI state
machine which handles corner cases not handled by other crates.
Performance
fast-strip-ansi the fastest and most correct library for stripping ANSI escape
sequences.
Note that fast-strip-ansi has wider support for ANSI escape sequences than
most crates but is still the fastest option.
It is significantly faster than strip-ansi and strip-ansi-escapes in all
modes.
