vesta 0.1.0

Extensible pattern matching

Rust license: MIT documentation

A vesta, otherwise known as a match case, is a small container for matches, named after the Roman goddess of the hearth.

Vesta is a crate for extensibly matching cases in Rust.

By implementing Match and [Case] for some type (or better yet, correctly deriving them using the Match derive macro), you can pattern-match on that type using the [case!] macro almost like using the match keyword built into Rust.

However, Vesta's [case!] macro is more general than match, because [Match] and [Case] are traits! This means you can enable pattern-matching for types which are not literally implemented as enums, and you can write code which is generic over any type that is pattern-matchable.
