Cases

Case	Payload	Description
no-such-store	—	The host does not recognize the store identifier requested.
access-denied	—	The requesting component does not have access to the specified store (which may or may not exist).
invalid-argument	—	The request was malformed or self-contradictory, e.g. a `cas.swap` whose `cas-options` sets no precondition.
precondition-failed	—	A conditional operation did not meet its precondition, e.g. a `set` with `if-not-exists` against a key that already exists.
timeout	—	The operation did not complete within the host- or backend-imposed time limit.
store-unavailable	—	The store is currently unreachable or otherwise unavailable. The operation may succeed if retried later.
quota-exceeded	—	The operation was rejected because a quota or rate limit was exceeded.
other	string	Some other implementation-specific error has occurred (e.g. I/O). Used for backend-specific failures that do not map to a named case above.
