Expand description

The interface into local storage (e.g., the Aptos DB) used by the storage server to handle client requests.

Required Methods

Returns a data summary of the underlying storage state.

Returns a list of transactions with a proof relative to the proof_version. The transaction list is expected to start at start_version and end at end_version (inclusive). If include_events is true, events are also returned.

Returns a list of epoch ending ledger infos, starting at start_epoch and ending at the expected_end_epoch (inclusive). For example, if start_epoch is 0 and end_epoch is 1, this will return 2 epoch ending ledger infos (ending epoch 0 and 1, respectively).

Returns a list of transaction outputs with a proof relative to the proof_version. The transaction output list is expected to start at start_version and end at end_version (inclusive).

Returns the number of accounts in the account state tree at the specified version.

Returns a chunk holding a list of account states starting at the specified start_account_index and ending at end_account_index (inclusive).
