Struct PersistentConsensusState 

pub struct PersistentConsensusState { /* private fields */ }

Persistent consensus state store backed by vsdb

Implementations

impl PersistentConsensusState

pub fn open(data_dir: &Path) -> Result<Self>

Opens an existing consensus state store or creates a fresh one.

Must be called after vsdb::vsdb_set_base_dir. The instance ID of the internal collection is stored in data_dir/consensus_state.meta (8 bytes: one little-endian u64). On first run the file is created; on subsequent runs the collection is recovered via MapxOrd::from_meta.

pub fn new() -> Self

Creates a new in-memory consensus state without any persistent meta file. Intended for unit tests only; use Self::open in production.
