Struct `Comparator`

pub struct Comparator { pub op: Op, pub major: u64, pub minor: Option<u64>, pub patch: Option<u64>, pub pre: Prerelease }

A pair of comparison operator and partial version, such as >=1.2. Forms one piece of a VersionReq.

Fields

op: Op
major: u64
minor: Option<u64>
patch: Option<u64>: Patch is only allowed if minor is Some.
pre: Prerelease: Non-empty pre-release is only allowed if patch is Some.
