Structs

Used by SnapshotPackagerService and SnapshotGossipManager, this struct adds type safety to ensure a full snapshot hash is pushed to the right CRDS.

IncrementalSnapshotHash

The hash used for snapshot archives

StartingSnapshotHashes

At startup, when loading from snapshots, the starting snapshot hashes need to be passed to SnapshotPackagerService, which is in charge of pushing the hashes to CRDS. This struct wraps up those values make it easier to pass from bank_forks_utils, through validator, to SnapshotPackagerService.
