func (Range) String

func (r Range) String() string

String returns a string representation of the range.

type T

type T uint32

func Common

func Common(ctx *context.T, l, r Range) (T, error)

Common returns the highest common version between the provided ranges. Returns an error if no such version exists.

func (*T) Set

func (v *T) Set(s string) error
