Focus: Main/Home screen (TUI)

Notes

As said in a previous issue, I like where I was going with the gui layout.

It contained a sidebar, which acted as a list with cards for each joined room/dm.
The cards had a display name, and the last message, akin to actual IM clients like element on mobile or disc*rd.

Avatar can be skipped/replaced with placeholder square with initials of the display name, or I could look at using the terminal image protocols.

The room data was cached in a HashMap<OwnedRoomId, RoomData>.

Relevant stuff from #19

Last message enum:

 /// Last received message event in a room
 #[derive(Clone, Debug, PartialEq)]
 pub enum LastMessage {
     Text(SharedString),
     Image,
     Video,
     Audio,
     File(SharedString), // filename
     Unknown,
     None,
 }

Room info for the UI:

 /// Holds UI-relevant room data to display as a card or on the sidebar
 #[derive(Clone, Debug, Default, PartialEq)]
 pub struct RoomData {
     pub display_name: Option<SharedString>,
     pub avatar: Option<Arc<gpui::Image>>,
     pub last_msg: Option<LastMessage>,
 }

Getting the last message:

                 let last_msg = last_event.and_then(|event| {
                     use matrix_sdk::ruma::events::{
                         AnySyncMessageLikeEvent, AnySyncTimelineEvent,
                         room::message::{MessageType, SyncRoomMessageEvent},
                     };
                     // only handle stuff that can be displayed in ui

(see L362-387 for full expr)

Getting the room avatar to render:

                 // Thumbnail = less memory (relatively anyway), less unneeded network I/O
                 // also renders much nicer, downscaling a full file in the app makes it veeeeeery aliased >_<
                 let avatar = if not_rate_limited {
                     tracing::debug!(
                         "Not rate limited, downloading {:?} ({:?})",
                         &display_name,
                         &room_id
                     );
                     // FIXME: i don't know why but *some* rooms simply refuse to return an avatar
                     room.avatar(matrix_sdk::media::MediaFormat::Thumbnail(
                         MediaThumbnailSettings::with_method(ruma::media::Method::Crop, 96u32.into(), 96u32.into()),
                     ))

(see L317-L356 for the full expr)

Note that the last message/avatar expressions would just be their own functions, probably, if ported. The linked snippets are a part of the function

pub fn get_room_data(&mut self, room: Room, cx: &mut Context<Self>) {
