## Executive Summary
Research: parse_number() as a SQLite extension: C vs Rust I was out walking the dog when I got curious about how easy/difficult it would be to write a SQLite C extension that adds a parse_number() function for turning strings like.

## Why It Matters (Strategic Analysis)
The findings demonstrate that standard library string conversion bottlenecks like C's strtod exert a greater impact on extension latency than fundamental language overhead. Prompt-guided micro-optimization enables tiny, low-footprint C extensions to achieve top-tier throughput without incurring Rust's heavy binary size penalty.
