Struct matrix_sdk_ui::room_list_service::Room

pub struct Room { /* private fields */ }

A room in the room list.

It’s cheap to clone this type.

Implementations

impl Room

pub fn id(&self) -> &RoomId

Get the room ID.

pub fn cached_display_name(&self) -> Option<String>

Get a computed room name for the room.

pub fn inner_room(&self) -> &Room

Get the underlying matrix_sdk::Room.

pub fn timeline(&self) -> Option<Arc<Timeline>>

Get the timeline of the room if one exists.

pub fn is_timeline_initialized(&self) -> bool

Get whether the timeline has been already initialised or not.

pub async fn init_timeline_with_builder( &self, builder: TimelineBuilder, ) -> Result<(), Error>

Initialize the timeline of the room with an event type filter so only some events are returned. If a previous timeline exists, it’ll return an error. Otherwise, a Timeline will be returned.

pub async fn latest_event(&self) -> Option<EventTimelineItem>

Get the latest event in the timeline.

The latest event comes first from the Timeline, it can be a local or a remote event. Note that the Timeline can have more information esp. if it has run a backpagination for example. Otherwise if the Timeline doesn’t have any latest event, it comes from the cache. This method does not fetch any events or calculate anything — if it’s not already available, we return None.

Reminder: this method also returns None is the latest event is not suitable for use in a message preview.

pub async fn default_room_timeline_builder( &self, ) -> Result<TimelineBuilder, Error>

Create a new TimelineBuilder with the default configuration.

If the room was synced before some initial events will be added to the TimelineBuilder.

Methods from Deref<Target = Room>

pub async fn make_edit_event( &self, event_id: &EventId, new_content: EditedContent, ) -> Result<AnyMessageLikeEventContent, EditError>

Create a new edit event for the target event id with the new content.

The event can then be sent with Room::send or a crate::send_queue::RoomSendQueue.

pub async fn leave(&self) -> Result<(), Error>

Leave this room.

Only invited and joined rooms can be left.

pub async fn join(&self) -> Result<(), Error>

Join this room.

Only invited and left rooms can be joined via this method.

pub fn client(&self) -> Client

Get the inner client saved in this room instance.

Returns the client this room is part of.

pub fn is_synced(&self) -> bool

Get the sync state of this room, i.e. whether it was fully synced with the server.

pub async fn avatar( &self, format: MediaFormat, ) -> Result<Option<Vec<u8>>, Error>

Gets the avatar of this room, if set.

Returns the avatar. If a thumbnail is requested no guarantee on the size of the image is given.

Arguments

• format - The desired format of the avatar.

Examples

let client = Client::new(homeserver).await.unwrap();
client.matrix_auth().login_username(user, "password").send().await.unwrap();
let room_id = room_id!("!roomid:example.com");
let room = client.get_room(&room_id).unwrap();
if let Some(avatar) = room.avatar(MediaFormat::File).await.unwrap() {
    std::fs::write("avatar.png", avatar);
}

pub async fn messages( &self, options: MessagesOptions, ) -> Result<Messages, Error>

Sends a request to /_matrix/client/r0/rooms/{room_id}/messages and returns a Messages struct that contains a chunk of room and state events (RoomEvent and AnyStateEvent).

With the encryption feature, messages are decrypted if possible. If decryption fails for an individual message, that message is returned undecrypted.

Examples

use matrix_sdk::{room::MessagesOptions, Client};

let options =
    MessagesOptions::backward().from("t47429-4392820_219380_26003_2265");

let mut client = Client::new(homeserver).await.unwrap();
let room = client.get_room(room_id!("!roomid:example.com")).unwrap();
assert!(room.messages(options).await.is_ok());

pub fn add_event_handler<Ev, Ctx, H>(&self, handler: H) -> EventHandlerHandle

where Ev: SyncEvent + DeserializeOwned + Send + 'static, H: EventHandler<Ev, Ctx>,

Register a handler for events of a specific type, within this room.

This method works the same way as Client::add_event_handler, except that the handler will only be called for events within this room. See that method for more details on event handler functions.

room.add_event_handler(hdl) is equivalent to client.add_room_event_handler(room_id, hdl). Use whichever one is more convenient in your use case.

pub fn subscribe_to_updates(&self) -> Receiver<RoomUpdate>

Subscribe to all updates for this room.

The returned receiver will receive a new message for each sync response that contains updates for this room.

pub fn subscribe_to_typing_notifications( &self, ) -> (EventHandlerDropGuard, Receiver<Vec<OwnedUserId>>)

Subscribe to typing notifications for this room.

The returned receiver will receive a new vector of user IDs for each sync response that contains ‘m.typing’ event. The current user ID will be filtered out.

pub async fn subscribe_to_identity_status_changes( &self, ) -> Result<impl Stream<Item = Vec<IdentityStatusChange>>, Error>

Subscribe to updates about users who are in “pin violation” i.e. their identity has changed and the user has not yet acknowledged this.

The returned receiver will receive a new vector of IdentityStatusChange each time a /keys/query response shows a changed identity for a member of this room, or a sync shows a change to the membership of an affected user. (Changes to the current user are not directly included, but some changes to the current user’s identity can trigger changes to how we see other users’ identities, which will be included.)

The first item in the stream provides the current state of the room: each member of the room who is not in “pinned” or “verified” state will be included (except the current user).

If the changed_to property of an IdentityStatusChange is set to PinViolation then a warning should be displayed to the user. If it is set to Pinned then no warning should be displayed.

Note that if a user who is in pin violation leaves the room, a Pinned update is sent, to indicate that the warning should be removed, even though the user’s identity is not necessarily pinned.

pub async fn event( &self, event_id: &EventId, request_config: Option<RequestConfig>, ) -> Result<TimelineEvent, Error>

Fetch the event with the given EventId in this room.

It uses the given RequestConfig if provided, or the client’s default one otherwise.

pub async fn event_with_context( &self, event_id: &EventId, lazy_load_members: bool, context_size: UInt, request_config: Option<RequestConfig>, ) -> Result<EventWithContextResponse, Error>

Fetch the event with the given EventId in this room, using the /context endpoint to get more information.

pub async fn is_encrypted(&self) -> Result<bool, Error>

Check whether this room is encrypted. If the room encryption state is not synced yet, it will send a request to fetch it.

Returns true if the room is encrypted, otherwise false.

pub async fn sync_members(&self) -> Result<(), Error>

Sync the member list with the server.

This method will de-duplicate requests if it is called multiple times in quick succession, in that case the return value will be None. This method does nothing if the members are already synced.

pub async fn get_member( &self, user_id: &UserId, ) -> Result<Option<RoomMember>, Error>

Get a specific member of this room.

Note: This method will fetch the members from the homeserver if the member list isn’t synchronized due to member lazy loading. Because of that it might panic if it isn’t run on a tokio thread.

Use get_member_no_sync() if you want a method that doesn’t do any requests.

Arguments

• user_id - The ID of the user that should be fetched out of the store.

pub async fn get_member_no_sync( &self, user_id: &UserId, ) -> Result<Option<RoomMember>, Error>

Get a specific member of this room.

Note: This method will not fetch the members from the homeserver if the member list isn’t synchronized due to member lazy loading. Thus, members could be missing.

Use get_member() if you want to ensure to always have the full member list to chose from.

Arguments

• user_id - The ID of the user that should be fetched out of the store.

pub async fn members( &self, memberships: RoomMemberships, ) -> Result<Vec<RoomMember>, Error>

Get members for this room, with the given memberships.

Note: This method will fetch the members from the homeserver if the member list isn’t synchronized due to member lazy loading. Because of that it might panic if it isn’t run on a tokio thread.

Use members_no_sync() if you want a method that doesn’t do any requests.

pub async fn members_no_sync( &self, memberships: RoomMemberships, ) -> Result<Vec<RoomMember>, Error>

Get members for this room, with the given memberships.

Note: This method will not fetch the members from the homeserver if the member list isn’t synchronized due to member lazy loading. Thus, members could be missing.

Use members() if you want to ensure to always get the full member list.

pub async fn get_state_events( &self, event_type: StateEventType, ) -> Result<Vec<RawAnySyncOrStrippedState>, Error>

Get all state events of a given type in this room.

The typing notice remains active for 4s. It can be deactivate at any point by setting typing to false. If this method is called while the typing notice is active nothing will happen. This method can be called on every key stroke, since it will do nothing while typing is active.

Arguments

• typing - Whether the user is typing or has stopped typing.

Examples

use std::time::Duration;

use matrix_sdk::ruma::api::client::typing::create_typing_event::v3::Typing;

pub async fn enable_encryption(&self) -> Result<(), Error>

Enable End-to-end encryption in this room.

This method will be a noop if encryption is already enabled, otherwise sends a m.room.encryption state event to the room. This might fail if you don’t have the appropriate power level to enable end-to-end encryption.

A sync needs to be received to update the local room state. This method will wait for a sync to be received, this might time out if no sync loop is running or if the server is slow.

Examples

let room_id = room_id!("!SVkFJHzfwvuaIEawgC:localhost");

if let Some(room) = client.get_room(&room_id) {
    room.enable_encryption().await?
}

pub async fn sync_up(&self)

Wait for the room to be fully synced.

This method makes sure the room that was returned when joining a room has been echoed back in the sync.

Warning: This waits until a sync happens and does not return if no sync is happening. It can also return early when the room is not a joined room anymore.

pub fn send( &self, content: impl MessageLikeEventContent, ) -> SendMessageLikeEvent<'_>

Send a message-like event to this room.

Returns the parsed response from the server.

If the encryption feature is enabled this method will transparently encrypt the event if this room is encrypted (except for m.reaction events, which are never encrypted).

Note: If you just want to send an event with custom JSON content to a room, you can use the send_raw() method for that.

If you want to set a transaction ID for the event, use .with_transaction_id() on the returned value before .awaiting it.

Arguments

• content - The content of the message event.

Examples

use matrix_sdk::ruma::{
    events::{
        macros::EventContent,
        room::message::{RoomMessageEventContent, TextMessageEventContent},
    },
    uint, MilliSecondsSinceUnixEpoch, TransactionId,
};

let content = RoomMessageEventContent::text_plain("Hello world");
let txn_id = TransactionId::new();

if let Some(room) = client.get_room(&room_id) {
    room.send(content).with_transaction_id(txn_id).await?;
}

// Custom events work too:
#[derive(Clone, Debug, Deserialize, Serialize, EventContent)]
#[ruma_event(type = "org.shiny_new_2fa.token", kind = MessageLike)]
struct TokenEventContent {
    token: String,
    #[serde(rename = "exp")]
    expires_at: MilliSecondsSinceUnixEpoch,
}

let content = TokenEventContent {
    token: generate_token(),
    expires_at: {
        let now = MilliSecondsSinceUnixEpoch::now();
        MilliSecondsSinceUnixEpoch(now.0 + uint!(30_000))
    },
};

if let Some(room) = client.get_room(&room_id) {
    room.send(content).await?;
}

pub fn send_raw<'a>( &'a self, event_type: &'a str, content: impl IntoRawMessageLikeEventContent, ) -> SendRawMessageLikeEvent<'a>

Send a message-like event with custom JSON content to this room.

Returns the parsed response from the server.

If the encryption feature is enabled this method will transparently encrypt the event if this room is encrypted (except for m.reaction events, which are never encrypted).

This method is equivalent to the send() method but allows sending custom JSON payloads, e.g. constructed using the serde_json::json!() macro.

If you want to set a transaction ID for the event, use .with_transaction_id() on the returned value before .awaiting it.

Arguments

• event_type - The type of the event.

• content - The content of the event as a raw JSON value. The argument type can be serde_json::Value, but also other raw JSON types; for the full list check the documentation of IntoRawMessageLikeEventContent.

Examples

use serde_json::json;

if let Some(room) = client.get_room(&room_id) {
    room.send_raw("m.room.message", json!({ "body": "Hello world" })).await?;
}

pub fn send_attachment<'a>( &'a self, filename: &'a str, content_type: &'a Mime, data: Vec<u8>, config: AttachmentConfig, ) -> SendAttachment<'a>

Send an attachment to this room.

This will upload the given data that the reader produces using the upload() method and post an event to the given room. If the room is encrypted and the encryption feature is enabled the upload will be encrypted.

This is a convenience method that calls the upload() and afterwards the send().

Arguments

• filename - The file name.

• content_type - The type of the media, this will be used as the content-type header.

• reader - A Reader that will be used to fetch the raw bytes of the media.

• config - Metadata and configuration for the attachment.

        "my_favorite_cat.jpg",
        &mime::IMAGE_JPEG,
        image,
        AttachmentConfig::new(),
    ).await?;
}

pub async fn update_power_levels( &self, updates: Vec<(&UserId, Int)>, ) -> Result<Response, Error>
