impl LmdbGlobalState

pub fn empty(
    environment: Arc<LmdbEnvironment>,

Trait Implementations

impl StateProvider for LmdbGlobalState

type Error = Error

type Reader = LmdbGlobalStateView

fn checkout(
    &self,
    state_hash: Blake2bHash
) -> Result<Option<Self::Reader>, Self::Error>

Checkouts to the post state of a specific block.

fn commit(
    &self,
    correlation_id: CorrelationId,
    prestate_hash: Blake2bHash,
    effects: AdditiveMap<Key, Transform>
) -> Result<CommitResult, Self::Error>

Applies changes and returns a new post state hash. block_hash is used for computing a deterministic and unique keys.
