Simon Willison compares C vs. Rust for SQLite number parsing extension

By PulseAugur Editorial · [1 sources] ·

Simon Willison explored the creation of a SQLite extension to parse numbers from strings, comparing implementations in C and Rust. Initially, the Rust version, using Rusqlite and sqlite-loadable-rs, was significantly larger but faster than the C extension. However, after further prompting, the AI developed a C function that matched or surpassed the Rust implementation's performance. The investigation was then formatted into a research report. AI
