Struct sp_state_machine::StorageTransactionCache

source · [−]

pub struct StorageTransactionCache<Transaction, H: Hasher, N: BlockNumber> { /* private fields */ }

Expand description

The storage transaction are calculated as part of the storage_root and changes_trie_storage_root. These transactions can be reused for importing the block into the storage. So, we cache them to not require a recomputation of those transactions.
