This lets us write functions which can either take an existing
owned OwnedChanTarget, or copy out of some other kind of ChanTarget
passed by reference.
Now keyed by Arc<BridgeConfig>, and the values can be errors.
Currently there is no implementation so there can't be any errors,
but the error enum will become nonempty.
This is a compromise between C tor (never escapes = signs) and the
spec (calls for escaping all = signs). In C tor there is no way to
actually construct a key with an = sign in it, so this difference
should be undetectable.
This code is _not_ conditional, since we want to support running
with a proxy even if we don't support pluggable transports.
We may eventually want to refactor this into a new create.
Now, instead of duplicate checks in various cases, we simply go
through the loop one last time.
This allows us to simplify some of our other logic around here.
This is necessary so that we can look up channels (open and pending)
by all of the Ids that we know about them.
The operations needed here are pretty complex: to get them right,
I've replaced most of the accessors on the inner `ChannelMap` with a
function that holds the lock while another `FnOnce` is called. This
still gets us the invariant that we can't accidentally await while
holding the lock on the `ChannelMap`.
I've removed the tests for the accessors that are no longer there.
There are some subtleties here. Now that we have more than one kind
of Id, it's possible to have a partial match. I've tried to explain
all these cases in the comments.
}
Even though channels are practically changeable, they use locks
internally so that you don't need a `&mut Channel` to send or
receive traffic. It makes sense for reparameterizing the channel to
also use a &self reference.
I'll need this so that I can store channels in an `ByRelayIds<>`
set, and still invoke their reparameterize methods.
This is mostly a testing only change for now too, but soon I'll use
it to deal with the fact that we need to know the IDs to actually
build a channel at all.
The `ByRelayIds` type doesn't have a type equivalent to
`hash_map::Entry`, since it's a set type rather than a map
type. Therefore, the only plausible way to do entry mutation will
be to remove the old entry and insert a new one. And so, we no
longer need a "poisoned" state.
Also, add a few tests for this and the other accessors.
We'll need this accessor to find whether we have any channels to
_any_ of the identities that we're trying to connect to.
