Required Methods

fn client_states( &self ) -> Result<Vec<(ClientId, ClientStateRef<Self>)>, ContextError>

Returns the list of all clients.

fn consensus_states( &self, client_id: &ClientId ) -> Result<Vec<(Height, ConsensusStateRef<Self>)>, ContextError>

Returns the list of all consensus states for the given client.

fn consensus_state_heights( &self, client_id: &ClientId ) -> Result<Vec<Height>, ContextError>

Returns the list of all heights at which consensus states for the given client are.

fn connection_ends(&self) -> Result<Vec<IdentifiedConnectionEnd>, ContextError>

Returns the list of all connection ends.

fn client_connection_ends( &self, client_id: &ClientId ) -> Result<Vec<ConnectionId>, ContextError>

Returns the list of all connection ids of the given client.

fn channel_ends(&self) -> Result<Vec<IdentifiedChannelEnd>, ContextError>

Returns the list of all channel ends.

fn packet_commitments( &self, channel_end_path: &ChannelEndPath ) -> Result<Vec<PacketState>, ContextError>

Returns the list of all packet commitments for the given channel end.

fn packet_acknowledgements( &self, channel_end_path: &ChannelEndPath, sequences: impl ExactSizeIterator<Item = Sequence> ) -> Result<Vec<PacketState>, ContextError>

Filters the list of packet sequences for the given channel end that are acknowledged. Returns all the packet acknowledgements if sequences is empty.

fn unreceived_packets( &self, channel_end_path: &ChannelEndPath, sequences: impl ExactSizeIterator<Item = Sequence> ) -> Result<Vec<Sequence>, ContextError>

Filters the packet sequences for the given channel end that are not received.

fn unreceived_acks( &self, channel_end_path: &ChannelEndPath, sequences: impl ExactSizeIterator<Item = Sequence> ) -> Result<Vec<Sequence>, ContextError>

Filters the list of packet sequences for the given channel end whose acknowledgement is not received. Returns all the unreceived acknowledgements if sequences is empty.
