Enum SnapshotNamespace 

pub enum SnapshotNamespace {
    Branch,
    Tag,
    Checkpoint,
    Custom(Vec<u8>),
}

Namespace used to derive stable named-root keys for snapshots.

Variants

Branch

Mutable branch-style snapshots, stored under refs/heads/.

Tag

Tag-style snapshots, stored under refs/tags/.

Checkpoint

Checkpoint snapshots, stored under refs/checkpoints/.

Custom(Vec<u8>)

Application-defined root namespace.
