Struct semver::Comparator

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

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.
