Crate hamelin_lib 

Hamelin core library — parser, AST, type-checker, and translation logic.

Start with parse to get an AST, then type_check to type-check it. Each function has a _with_options variant that takes an options struct built via bon::Builder for customising behaviour (interner, provider, time range, etc.).

All functions return WithTranslationErrors<T> which can be converted to Result via .result(), or destructured to access .output and .errors.
