Audit of anstyle 1.0.14, a small #![no_std] Rust crate providing core types for ANSI text-styling escape codes, used as a vocabulary crate by clap and the anstream ecosystem. No runtime deps, no build script, no I/O, no network. One unsafe block (str::from_utf8_unchecked on a fixed-size buffer that only ever holds ASCII digits and &'static str bytes) is documented and sound. No findings. Safe to use.
