Accidental Functional Programming in Rust
summary
An open-source Rust library called Codeless Tools validates and standardizes clinical code lists at load time, returning a typed Result as value or a specific code-list error so mistakes surface before long runs. It uses enums for errors, iterator chaining and pattern matching to express pipelines without mutation, and exposes Python/R bindings so researchers call identical Rust logic. Real gains show up in practice — inspired by Polars, some workloads drop from 2 hours → 5 minutes.
