Required methods

fn connection_end(&self, conn_id: &ConnectionId) -> Option<ConnectionEnd>[src]

Returns the ConnectionEnd for the given identifier conn_id.

fn client_state(&self, client_id: &ClientId) -> Option<AnyClientState>[src]

Returns the ClientState for the given identifier client_id.

fn host_current_height(&self) -> Height[src]

Returns the current height of the local chain.

fn host_oldest_height(&self) -> Height[src]

Returns the oldest height available on the local chain.

fn commitment_prefix(&self) -> CommitmentPrefix[src]

Returns the prefix that the local chain uses in the KV store.

fn client_consensus_state(
    &self,
    client_id: &ClientId,
    height: Height
) -> Option<AnyConsensusState>[src]

Returns the ConsensusState that the given client stores at a specific height.

fn host_consensus_state(&self, height: Height) -> Option<AnyConsensusState>[src]

Returns the ConsensusState of the host (local) chain at a specific height.

fn connection_counter(&self) -> u64[src]

Returns a counter on how many connections have been created thus far. The value of this counter should increase only via method ConnectionKeeper::increase_connection_counter.

Provided methods

fn get_compatible_versions(&self) -> Vec<Version>[src]

Function required by ICS 03. Returns the list of all possible versions that the connection handshake protocol supports.

fn pick_version(
    &self,
    supported_versions: Vec<Version>,
    counterparty_candidate_versions: Vec<Version>
) -> Option<Version>[src]

Function required by ICS 03. Returns one version out of the supplied list of versions, which the connection handshake protocol prefers.
