 # Frizbee
 
-Frizbee is a SIMD fuzzy string matcher written in Rust. The core of the algorithm uses Smith-Waterman with affine gaps, similar to FZF, but with many of the scoring bonuses from FZY. In the included benchmark, with typo resistance disabled, it outperforms nucleo by ~2x (18.4us vs 35.8us). It matches against characters directly, ignoring unicode.
