Variants§

§

Exact

operator = (or no operator) : Allows only one exact version number. Cannot be combined with other conditions.

§

Different

operator != : Excludes an exact version number.

§

Greater

operator > : Comparisons against a specified version, allowing versions for which the comparison is true. “Greater” requests newer versions.

§

GreaterEq

operator >= : Comparisons against a specified version, allowing versions for which the comparison is true.

§

Less

operator < : Comparisons against a specified version, allowing versions for which the comparison is true. “Less” requests older versions.

§

LessEq

operator <= : Comparisons against a specified version, allowing versions for which the comparison is true.

§

RightMost

operator ~> : Allows only the rightmost version component to increment. For example, to allow new patch releases within a specific minor release, use the full version number: ~> 1.0.4 will allow installation of 1.0.5 and 1.0.10 but not 1.1.0.

impl PartialEq<Operator> for Operator

source§

fn eq(&self, other: &Operator) -> bool
