Enum State 

Source 
pub enum State {
    Idle,
    Running,
    Terminated,
    Error(Arc<Error>),
    Offline,
}
Expand description

Current state of the application.

This is a high-level state indicating what’s the status of the underlying syncs. The application starts in State::Running mode, and then hits a terminal state State::Terminated (if it gracefully exited) or State::Error (in case any of the underlying syncs ran into an error).

This can be observed with SyncService::state.

Variants§

§

Idle

The service hasn’t ever been started yet, or has been stopped.

§

Running

The underlying syncs are properly running in the background.

§

Terminated

Any of the underlying syncs has terminated gracefully (i.e. be stopped).

§

Error(Arc<Error>)

Any of the underlying syncs has ran into an error.

The associated Error is inside an Arc to (i) make State cloneable, and to (ii) not make it heavier.

§

Offline

The service has entered offline mode. This state will only be entered if the SyncService has been built with the SyncServiceBuilder::with_offline_mode setting.

The SyncService will enter the offline mode if syncing with the server fails, it will then periodically check if the server is available using the /_matrix/client/versions endpoint.

Once the SyncService receives a 200 response from the /_matrix/client/versions endpoint, it will go back into the State::Running mode and attempt to sync again.

Calling SyncService::start() while in this state will abort the /_matrix/client/versions checks and attempt to sync immediately.

Calling SyncService::stop() will abort the offline mode and the SyncService will go into the State::Idle mode.
