Why do I find Rust inadequate for codecs?

The post discusses the author's preference for implementing codecs in C over Rust due to performance considerations. It outlines Rust's memory safety features and efficiency, but also highlights its limitations for low-level, performance-sensitive tasks such as codecs. Examples from existing codec implementations in PAQ8, bzip3, and LZ4 illustrate the performance-critical nature of these applications and how Rust's bounds checks and ownership model may introduce overheads. The author concludes that C remains more ergonomic for these specific needs.
