This allows account manager to construct a single event channel and
inject it into all created contexts instead of aggregating events from
separate event emitters.
This makes sure that under normal circumstances the LoginParam struct
is always fully validated, ensure future use does not have to be
careful with this.
The brittle handling of `server_flags` is also abstraced away from
users of it and is now handled entirely internally, as the flags is
really only a boolean a lot of the flag parsing complexity is removed.
The OAuth2 flag is moved into the ServerLoginParam struct as it really
belongs in there.
New ratelimiter module counts number of sent messages and calculates
the time until more messages can be sent.
Rate limiter is currently applied only to MDNs. Other messages are
sent without rate limiting even if quota is exceeded, but MDNs are not
sent until ratelimiter allows sending again.
* force a reason when calling `set_msg_failed()`
the string is displayed to the user,
so even _some_ context as "NDN without further details"
is better than an empty string.
* make clippy happy
* add CHANGELOG entry
* clarify webxdc reference wrt info-messages
* add from_id parameter to add_info_msg_with_cmd()
* flag webxdc-info-messages as such
* set from_id to sender for webxdc-info-messages
* test additional webxdc info properties
* do not add series of similar info messages
instead, if on adding the last info message
is already from the same webxdc and sender,
just update the text
* test cleanup of webxdc info messages series
* update changelog
* make clippy happy
there is no real complexity in the args,
so allowing one more arg is probably fine.
if really wanted, we can refactor the function in another pr;
this pr is already complex enough :)
* use cleaner function names and comments
* clarify CHANGELOG
Not completely sure it's worth it since some other dependencies still
depend on it. Anyway, proc macros are said to be bad for compile times, I just typed out what the proc macro generates and it's only 8 more lines, and we're already doing it this way in e.g. action_by_contact() and collect_texts_recursive() (the latter needs the boxed future both for the trait and for recursion).
