Struct cfxcore::pos::state_sync::shared_components::SyncState

pub struct SyncState { /* private fields */ }

Expand description

SyncState contains the following fields:

committed_ledger_info holds the latest certified ledger info (committed to storage), i.e., the ledger info for the highest version for which storage has all ledger state.
synced_trees holds the latest transaction accumulator and state tree (which may or may not be committed to storage), i.e., some ledger state for the next highest ledger info version is missing.
trusted_epoch_state corresponds to the current epoch if the highest committed ledger info (committed_ledger_info) is in the middle of the epoch, otherwise, it corresponds to the next epoch if the highest committed ledger info ends the epoch.

Note: committed_ledger_info is used for helping other Diem nodes synchronize (i.e., it corresponds to the highest version we have a proof for in storage). synced_trees is used locally for retrieving missing chunks for the local storage.

Implementations§
