Module checkpoint::wrappers

Structs

ChecksumWrapper	Adds checksum verification to checkpoint data.
GuardWrapper	Protects checkpoint data by ensuring that no two uncommitted checkpoints can have the same identifier and that committed checkpoints cannot be removed while in use (i.e. have a binding created by either the commit_checkpoint method or the load_checkpoint method).
HmacWrapper	Adds HMAC verification to checkpoint data.
