Expand description

A context supplying all the necessary write-only dependencies (i.e., storage writing facility) for processing any ChannelMsg.

Required Methods

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

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.
