ForSorting returns a string that encodes version, so that comparing two such strings follows SemVer precedence, https://semver.org clause 11.

IsIncompatible reports whether a valid version v is an incompatible version.

IsPseudo reports whether a valid version v is a pseudo-version.

Later reports whether v1 is later than v2, using semver but preferring release versions to pre-release versions, and both to pseudo-versions.

LatestOf returns the latest version of a module from a list of versions, using the go command's definition of latest: semver is observed, except that release versions are preferred to prerelease, and both are preferred to pseudo-versions.

LatestVersion finds the latest version of a module using the same algorithm as the Go command.

ParseType returns the Type of a given a version.

RemoveIf returns a copy of s that omits all values for which f returns true.

Latest signifies the latest available version in requests to the proxy client.

Main represents the main branch.

Master represents the master branch.

TypePrerelease is a version with a prerelease.

TypePseudo appears to have a prerelease of the form <commit date>-<commit hash>.

TypeRelease is a normal release.

Type defines the version types a module can have.
