Performance of Rust's match vs. lookup tables

The post explores the performance differences between using Rust's `match` statements and lookup tables for certain bioinformatics algorithms, particularly focusing on how different methods perform in specific tasks. Through detailed benchmark tests and analysis of generated assembly and LLVM IR code, it concludes that inlined lookups are generally faster due to requiring fewer instructions. Additionally, the use of the `lazy_static` crate introduces overhead that can affect performance measurements.
