Functions

func Compare

func Compare(a, b Interface) int

Compare compares the version details of two packages. Versions are compared by Epoch, Version and Release in descending order of precedence.

If a is more recent than b, 1 is returned. If a is less recent than b, -1 is returned. If a and b are equal, 0 is returned.

This function does not consider if the two packages have the same name or if either package has been made obsolete by the other.

Types

type Interface

type Interface interface {
	Name() string
	Epoch() int
	Version() string
	Release() string
}

Interface is an interface which holds version information for a single package.
