Enum ExecutedTrieUpdates 

Source 
pub enum ExecutedTrieUpdates {
    Present(Arc<TrieUpdates>),
    Missing,
}
Expand description

Trie updates that result from calculating the state root for the block.

Variants§

§

Present(Arc<TrieUpdates>)

Trie updates present. State root was calculated, and the trie updates can be applied to the database.

§

Missing

Trie updates missing. State root was calculated, but the trie updates cannot be applied to the current database state. To apply the updates, the state root must be recalculated, and new trie updates must be generated.

This can happen when processing fork chain blocks that are building on top of the historical database state. Since we don’t store the historical trie state, we cannot generate the trie updates for it.
