// Implementations of this interface will be called when data is received, when
// data should be skipped/forgotten or when sequence number should be reset.
//
// As a result of these operations - mainly when data is received - the
// implementations of this interface should notify when a message has been
// assembled, by calling the provided callback of type `OnAssembledMessage`. How
// it assembles messages will depend on e.g. if a message was sent on an ordered
// or unordered stream.
//
// Implementations will - for each operation - indicate how much additional
// memory that has been used as a result of performing the operation. This is
// used to limit the maximum amount of memory used, to prevent out-of-memory
// situations.
