Struct BackupProvider

Source 
pub struct BackupProvider {
    _endpoint: Endpoint,
    node_addr: NodeAddr,
    auth_token: String,
    handle: JoinHandle<Result<()>>,
    _drop_guard: DropGuard,
}
Expand description

Provide or send a backup of this device.

This creates a backup of the current device and starts a service which offers another device to download this backup.

This does not make a full backup on disk, only the SQLite database is created on disk, the blobs in the blob directory are not copied.

This starts a task which acquires the global “ongoing” mutex. If you need to stop the task use the Context::stop_ongoing mechanism.

Fields§

§_endpoint: Endpoint

iroh endpoint.

§node_addr: NodeAddr

iroh address.

§auth_token: String

Authentication token that should be submitted to retrieve the backup.

§handle: JoinHandle<Result<()>>

Handle for the task accepting backup transfer requests.

§_drop_guard: DropGuard

Guard to cancel the provider on drop.

Implementations§

Source§

impl BackupProvider

Source

pub async fn prepare(context: &Context) -> Result<Self>

Prepares for sending a backup to a second device.

Before calling this function all I/O must be stopped so that no changes to the blobs or database are happening, this is done by calling the Accounts::stop_io or Context::stop_io APIs first.

This will acquire the global “ongoing process” mutex, which can be used to cancel the process.

Source

async fn handle_connection( context: Context, conn: Connecting, auth_token: String, dbfile: Arc<TempPathGuard>, ) -> Result<()>

Source

async fn accept_loop( context: Context, endpoint: Endpoint, auth_token: String, cancel_token: Receiver<()>, drop_token: CancellationToken, dbfile: TempPathGuard, )

Source

pub fn qr(&self) -> Qr

Returns a QR code that allows fetching this backup.

This QR code can be passed to get_backup on a (different) device.
