Trait used for the top-level execute and dispatch entrypoints in the ibc-core crate.

Required Associated Types

type E: ClientExecutionContext

Required Methods

fn get_client_execution_context(&mut self) -> &mut Self::E

Retrieve the context that implements all clients’ ExecutionContext.

fn increase_client_counter(&mut self) -> Result<(), ContextError>

Called upon client creation. Increases the counter which keeps track of how many clients have been created. Should never fail.

fn store_connection( &mut self, connection_path: &ConnectionPath, connection_end: ConnectionEnd ) -> Result<(), ContextError>

Stores the given connection_end at path

fn store_connection_to_client( &mut self, client_connection_path: &ClientConnectionPath, conn_id: ConnectionId ) -> Result<(), ContextError>

Stores the given connection_id at a path associated with the client_id.

fn increase_connection_counter(&mut self) -> Result<(), ContextError>

Called upon connection identifier creation (Init or Try process). Increases the counter which keeps track of how many connections have been created. Should never fail.

fn store_packet_commitment( &mut self, commitment_path: &CommitmentPath, commitment: PacketCommitment ) -> Result<(), ContextError>

Stores the given packet commitment at the given store path

fn delete_packet_commitment( &mut self, commitment_path: &CommitmentPath ) -> Result<(), ContextError>

Deletes the packet commitment at the given store path

fn store_packet_receipt( &mut self, receipt_path: &ReceiptPath, receipt: Receipt ) -> Result<(), ContextError>

Stores the given packet receipt at the given store path

fn store_packet_acknowledgement( &mut self, ack_path: &AckPath, ack_commitment: AcknowledgementCommitment ) -> Result<(), ContextError>

Stores the given packet acknowledgement at the given store path

fn delete_packet_acknowledgement( &mut self, ack_path: &AckPath ) -> Result<(), ContextError>

Deletes the packet acknowledgement at the given store path

fn store_channel( &mut self, channel_end_path: &ChannelEndPath, channel_end: ChannelEnd ) -> Result<(), ContextError>

Stores the given channel_end at a path associated with the port_id and channel_id.

fn store_next_sequence_send( &mut self, seq_send_path: &SeqSendPath, seq: Sequence ) -> Result<(), ContextError>

Stores the given nextSequenceSend number at the given store path

fn store_next_sequence_recv( &mut self, seq_recv_path: &SeqRecvPath, seq: Sequence ) -> Result<(), ContextError>

Stores the given nextSequenceRecv number at the given store path

fn store_next_sequence_ack( &mut self, seq_ack_path: &SeqAckPath, seq: Sequence ) -> Result<(), ContextError>

Stores the given nextSequenceAck number at the given store path

fn increase_channel_counter(&mut self) -> Result<(), ContextError>

Called upon channel identifier creation (Init or Try message processing). Increases the counter which keeps track of how many channels have been created. Should never fail.

fn emit_ibc_event(&mut self, event: IbcEvent) -> Result<(), ContextError>

Emit the given IBC event

fn log_message(&mut self, message: String) -> Result<(), ContextError>

Log the given message.
