Enum CheckpointSelector 

Source 
pub enum CheckpointSelector {
    Latest,
    Sequence(u64),
    Action(u64),
}
Expand description

One scoped retained-history selection, independent of storage revisions.

Its serialized form uses kind and, for sequence/action selections, value.

Variants§

§

Latest

The latest eligible observation in the selected operation.

Run checkpoint reads use the current App checkpoint. Restore and child initializers use the latest saved successful or failed action.

§

Sequence(u64)

One exact immutable checkpoint sequence.

§

Action(u64)

The latest successful or failed observation of this action ordinal.
