fn store_connection_channels(
    &mut self,
    conn_id: ConnectionId,
    port_channel_id: &(PortId, ChannelId)
) -> Result<(), Error>[src]

fn store_channel(
    &mut self,
    port_channel_id: (PortId, ChannelId),
    channel_end: &ChannelEnd
) -> Result<(), Error>[src]

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

fn store_next_sequence_send(
    &mut self,
    port_channel_id: (PortId, ChannelId),
    seq: Sequence
) -> Result<(), Error>[src]

fn increase_channel_counter(&mut self)[src]

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.
