Function compute_block_trie_updates 

pub fn compute_block_trie_updates<Provider>(
    cache: &ChangesetCache,
    provider: &Provider,
    block_number: u64,
) -> Result<TrieUpdatesSorted, ProviderError>
where
    Provider: DBProvider + StageCheckpointReader + ChangeSetReader + StorageChangeSetReader + BlockNumReader,

Available on crate features trie and trie-db only.

Computes block trie updates using the changeset cache.

Algorithm

For block N:

1. Get cumulative trie reverts from block N+1 to db tip using the cache
2. Create an overlay cursor factory with these reverts (representing trie state after block N)
3. Walk through account trie changesets for block N
4. For each changed path, look up the current value using the overlay cursor
5. Walk through storage trie changesets for block N
6. For each changed path, look up the current value using the overlay cursor
7. Return the collected trie updates

Arguments

• cache - Handle to the changeset cache for retrieving trie reverts
• provider - Database provider for accessing changesets and block data
• block_number - Block number to compute trie updates for

Returns

Trie updates representing the state of trie nodes after the block was processed

Errors

Returns error if:

• Block number exceeds database tip
• Database access fails
• Cache retrieval fails
