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

case!] macro almost like using the
match keyword built into Rust.
However, Vesta's [
case!] macro is more general than
match, because [
Match] and [
are traits! This means you can enable pattern-matching for types which are not literally
enums, and you can write code which is generic over any type that is
