Method state_root

crates/proof/executor/src/db/mod.rs:105–121

Applies a [`BundleState`] changeset to the [`TrieNode`] and recomputes the state root hash. ## Takes - `bundle`: The [`BundleState`] changeset to apply to the trie DB. ## Returns - `Ok(B256)`: The new state root hash of the trie DB. - `Err(_)`: If the state root hash could not be computed.
