}

The sync state (§19.1). With several candidates, the first of Removed, NeedsReset, UpdateNeeded, SignedOut, NoAccess, FolderMissing, ClockWrong, StorageFull, OfflineWithUnsentChanges, Offline, Failed, Syncing, WaitingToSync, Synced shows; NotSynced comes before them all.

Variants

NotSynced

No storage location is recorded on this device.

Syncing

A running pass has read or claimed a slot, or a file is being sent or downloaded.

WaitingToSync(SyncWait)

Nothing moves, and the last pass was held back, at a slot that can’t apply yet or by a provider’s cooldown, or a file waits in the upload queue, or a write in the send queue: what the pass waits for, else what the first such file waits for, else what the write waits for.

Synced

The last pass reached the end of the sequence, every file this device uploads is stored, the send queue is empty, and nothing below holds: nothing waits.

Offline(SyncCause)

The last pass got no provider response.

OfflineWithUnsentChanges(SyncCause)

Offline, and the send queue holds a write or the upload queue a file.

SignedOut

A location is recorded, but this device holds no credentials for it (no cause), or storage refused them.

Fields

provider: CloudProvider

The recorded location’s provider.

cause: Option<SyncCause>

What refused the credentials; none when this device holds none.

NoAccess(SyncCause)

Signed in, but the account isn’t allowed.

StorageFull(SyncCause)

The provider’s quota is used up.

FolderMissing(SyncCause)

The storage folder or bucket is gone.

ClockWrong(SyncCause)

The device’s clock is too far from the provider’s.

UpdateNeeded(SyncCause)

A newer app or coven is needed.

Removed(SyncCause)

This device or its member was removed, or a joined store’s admission was refused (NotAdmitted, §13.2).

NeedsReset(SyncCause)

Another copy uses this device’s id, or its member keys were replaced.

Failed(SyncCause)

Any other failure, or a file that can’t be uploaded or read, whose pending record is the cause.

Trait Implementations

impl Clone for SyncState

fn clone(&self) -> SyncState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SyncState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for SyncState

fn eq(&self, other: &SyncState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
