Latest update (11-08 17:26): Simon Willison compares C and Rust SQLite parse_number() extensions

Overview: Simon Willison builds four SQLite extensions that implement parse_number(), which strips commas, currency signs and percent signs to produce numbers, in C and Rust. He reports that the optimized C version ran at 16 to 19 ns per row, about twice as fast as the Rust versions and faster than SQL replace(). He says the versions matched across 8 million fuzz checks.
