Required Methods

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

Returns the list of all clients.

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

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

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

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

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

Returns the list of all connection ends.

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

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

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

Returns the list of all channel ends.

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

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>, HostError>

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>, HostError>

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>, HostError>

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
