CheckpointAppendOutcome

pepper_sync::shardtree_ext

Enum CheckpointAppendOutcome 

Source 
pub enum CheckpointAppendOutcome {
    Appended,
    NotAboveNewest,
}
Expand description

Outcome of appending a checkpoint that records the tree’s current frontier position at a new height.

Variants§

§

Appended

The association between the id and the current frontier position was recorded.

§

NotAboveNewest

The id is not above the store’s newest checkpoint. The tree is unchanged. Appending stamps the current frontier, so recording it at or below an already-stamped height would duplicate or falsify the height-to-frontier record. Checkpoints for past heights travel with their own tree states through the order-agnostic channels instead (ShardTree::insert_tree’s per-subtree checkpoint maps, and the store-level ShardStore::add_checkpoint).
