Claude compares C and Rust builds of a SQLite extension
What happened
On November 9, Simon Willison reported using Claude Opus 5.5 to compare C and Rust implementations of the SQLite parse_number() extension. Two Rust versions were tested: one built with Rusqlite produced a 321 KB .so file, one built with sqlite-loadable-rs produced 298 KB, and the C version came in at just 14 KB. The C build is clearly smaller, but the performance comparison showed the Rust versions run faster. The report attributes that speed advantage to Rust's strtod equivalent, which runs at roughly twice the speed of the C implementation.

- Simon Willisonparse_number() as a SQLite extension: C vs Rust
Simon Willison 用 Claude Opus 5.5 对比了用 C 和 Rust 编写 SQLite parse_number() 扩展的差异：Rust 版 .so 文件为 321 KB（Rusqlite）和 298 KB（sqlite-loadable-rs），C 版仅 14 KB，但 Rust 版更快，原因是其 strtod 等价实现速度约为 C 的两倍。
