Struct Request

#[non_exhaustive]
pub struct Request {
    pub pos: Option<String>,
    pub conn_id: Option<String>,
    pub txn_id: Option<String>,
    pub timeout: Option<Duration>,
    pub lists: BTreeMap<String, List>,
    pub room_subscriptions: BTreeMap<OwnedRoomId, RoomSubscription>,
    pub extensions: Extensions,
}

Available on crate feature experimental-sliding-sync only.

Request type for the /sync endpoint.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

pos: Option<String>

A point in time to continue a sync from.

This is an opaque value taken from the pos field of a previous /sync response. A None value asks the server to start a new session (mind it can be costly)

conn_id: Option<String>

A unique string identifier for this connection to the server.

If this is missing, only one sliding sync connection can be made to the server at any one time. Clients need to set this to allow more than one connection concurrently, so the server can distinguish between connections. This must be provided with every request, if your client needs more than one concurrent connection.

Limitation: it must not contain more than 16 chars, due to it being required with every request.

txn_id: Option<String>

Allows clients to know what request params reached the server, functionally similar to txn IDs on /send for events.

timeout: Option<Duration>

The maximum time to poll before responding to this request.

None means no timeout, so virtually an infinite wait from the server.

lists: BTreeMap<String, List>

Lists of rooms we are interested by, represented by ranges.

room_subscriptions: BTreeMap<OwnedRoomId, RoomSubscription>

Specific rooms we are interested by.

It is useful to receive updates from rooms that are possibly out-of-range of all the lists (see Self::lists).

extensions: Extensions

Extensions.
