Expand description

State DB maintenance. See module description. Can be shared across threads.

Implementations

Create an instance of StateDb.

Add a new non-canonical block.

Finalize a previously inserted block.

Prevents pruning of specified block and its descendants. hint used for futher checking if the given block exists

Allows pruning of specified block.

Confirm that all changes made to commit sets are on disk. Allows for temporarily pinned blocks to be released.

Get a value from non-canonical/pruning overlay or the backing DB.

Revert all non-canonical blocks with the best block number. Returns a database commit or None if not possible. For archive an empty commit set is returned.

Remove specified non-canonical block. Returns a database commit or None if not possible.

Returns last canonicalized block.

Check if block is pruned away.

Reset in-memory changes to the last disk-backed state.
