Module codes

Expand description

Refusal and ending codes. The provider sends them as the code of an error body; see Refusal.

Constants§

CANCELLED: Subscription ending after the caller’s own Cancel. The provider may send it as the last frame, and the daemon may drop it because the caller asked to stop. A reader treats it, after its own Cancel, as the normal end.
CURSOR_EXPIRED: Read: after is older than the feed holds. The detail carries through, the newest cursor.
DRAINING: Subscribe: the provider is stopping.
INVALID_REQUEST: Read: limit is 0, or after is not a cursor the provider issued. Read and subscribe: the request names harness without session, or session without harness.
LAGGED: Subscription ending: the subscriber fell behind its queue bound. The detail carries through, the last notified cursor.
MALFORMED: The request did not decode, or it carries an unknown member.
NOT_PERMITTED: The caller is not an admitted reader (a local same-user app, or the operator’s phone relayed by the federation module).
RANGE_TOO_LARGE: Read: limit is above crate::MAX_READ_LIMIT.
READ_REFUSALS: Every code that refuses a read.
SUBSCRIBE_ENDINGS: Every code that ends an open subscription with an error.
SUBSCRIBE_REFUSALS: Every code that refuses opening a subscription.
SUBSCRIPTION_CAPACITY: Subscribe: more than 16 subscriptions would be open.
