pub(super) struct TunnelMutableState(Mutex<HashMap<UniqId, (LegId, Arc<MutableState>)>>);Expand description
The mutable state of a tunnel, shared between ClientCirc and Reactor.
NOTE(gabi): this mutex-inside-a-mutex might look suspicious,
but it is currently the best option we have for sharing
the circuit state with ClientCirc (and soon, with ClientTunnel).
In practice, these mutexes won’t be accessed very often
(they’re accessed for writing when a circuit is extended,
and for reading by the various ClientCirc APIs),
so they shouldn’t really impact performance.
Alternatively, the circuit state information could be shared
outside the reactor through a channel (passed to the reactor via a CtrlCmd),
but in #1840 @opara notes that involves making the ClientCirc accessors
(ClientCirc::path, ClientCirc::binding_key, etc.)
asynchronous, which will significantly complicate their callsites,
which would in turn need to be made async too.
We should revisit this decision at some point, and decide whether an async API would be preferable.
