When deserialization fails we fallback to providing the user with a
serde_json::RawValue, basically the json string. Ruma should handle all
events that conform to a matrix event shape correctly by either
converting them to their type or returning a custom event.
Redact message events according to spec and ruma types. Remove content
using events redact() method and insert the redacting event into the
event being redacted.
High-level summary of changes:
- Rewrite the disambiguation algorithm to simplify it.
- Fixes to state tracking, e.g. use `state_key` instead of `user_id` when
determining which member an event is acting on.
- Changes to `RoomMember`:
* Make `RoomMember` "dumber" and don't let it mutate itself. This came about
primarily because `update_profile` cannot live on `RoomMember` because it
needs some information from `Room`. The other few mutating methods then
looked odd so it seemed best to move them to `Room` so that the room takes
care of updating its members.
* Each `RoomMember` now contains all information to calculate its set of
names:
+ `.name()` (short/ergonomic but potentially ambiguous),
+ `.unique_name()` (unique but may be contain MXID when not necessary),
+ `.disambiguated_name()` (shortest possible while being unique).
- Add some logging using the `tracing` crate.
- Improvements to `EventBuilder`:
* Add a docstring.
* Make it clear itself when building a sync response so the same builder can
be reused for later sync responses.
- A few tests.
This makes more sense as all the required information is now available
on `RoomMember`. We also don't have to handle the case of the missing
member since now you have to actually get a `RoomMember` before you can
ask for their name.
