Functions

func CheckPacking

func CheckPacking(p upspin.Packer, entry *upspin.DirEntry) error

CheckPacking verifies that the DirEntry matches the packing type for Pack and Packlen.

func Lookup

func Lookup(p upspin.Packing) upspin.Packer

Lookup returns the implementation of the specified Packing, or nil if none is registered.

func LookupByName

func LookupByName(name string) upspin.Packer

LookupByName returns the implementation of the specified Packing, or nil if none is registered.

func Register

func Register(packer upspin.Packer) error

Register binds a Packing code to the implementation of its algorithm. It must be called in the init function of a Packer implementation. If multiple calls have the same Packing, Register will panic. TODO: One day, or in other languages, we may be able to bind lazily.
