aiocoap.transports.rfc8323common module¶
Common code for the tcp and the ws modules, both of which are based on RFC8323 mechanisms, but differ in their underlying protocol implementations (asyncio stream vs. websockets module) far enough that they only share small portions of their code
-
exception
aiocoap.transports.rfc8323common.
CloseConnection
¶ Bases:
Exception
Raised in RFC8323 common processing to trigger a connection shutdown on the TCP / WebSocket side.
The TCP / WebSocket side should send the exception’s argument on to the token manager, close the connection, and does not need to perform further logging.
-
class
aiocoap.transports.rfc8323common.
RFC8323Remote
¶ Bases:
object
Mixin for Remotes for all the common RFC8323 processing
Implementations still need the per-transport parts, especially a _send_message and an _abort_with implementation.

abort
(errormessage=None, bad_csm_option=None)¶
-
release
()¶ Send Release message, (not implemented:) wait for connection to be actually closed by the peer.
Subclasses should extend this to await closing of the connection, especially if they’d get into lock-up states otherwise (was would WebSockets).
