Function compute_block_trie_changesets 

pub fn compute_block_trie_changesets<Provider>(
    provider: &Provider,
    block_number: u64,
) -> Result<TrieUpdatesSorted, ProviderError>
where
    Provider: DBProvider + ChangeSetReader + StorageChangeSetReader + BlockNumReader + StorageSettingsCache,

Available on crate features trie-db and trie only.

Computes trie changesets for a block.

For block N, this reconstructs the trie as it existed after N, then calculates the trie updates needed to restore the state before N.

Errors

Returns an error if the block exceeds the database tip, database access fails, or state root computation fails.
