Vesta
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 enum
s,
and you can write code which is generic over any type that is pattern-matchable.
