Result of a remote procedure call.

Based on grpc_status_code.

Variants

Ok

Not an error; returned on success.

Cancelled

The operation was cancelled (typically by the caller).

Unknown

Unknown error. An example of where this error may be returned is if a Status value received from another address space belongs to an error-space that is not known in this address space. Also errors raised by APIs that do not return enough error information may be converted to this error.

InvalidArgument

Client specified an invalid argument. Note that this differs from FailedPrecondition. InvalidArgument indicates arguments that are problematic regardless of the state of the system (e.g., a malformed file name).

DeadlineExceeded

Deadline expired before operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire.

NotFound

Some requested entity (e.g., file or directory) was not found.

AlreadyExists

Some entity that we attempted to create (e.g., file or directory) already exists.

PermissionDenied

The caller does not have permission to execute the specified operation. PermissionDenied must not be used for rejections caused by exhausting some resource (use ResourceExhausted instead for those errors). PermissionDenied must not be used if the caller can not be identified (use Unauthenticated instead for those errors).

Unauthenticated

The request does not have valid authentication credentials for the operation.

ResourceExhausted

Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.

FailedPrecondition

Operation was rejected because the system is not in a state required for the operation's execution. For example, directory to be deleted may be non-empty, an rmdir operation is applied to a non-directory, etc.

Aborted

The operation was aborted, typically due to a concurrency issue like sequencer check failures, transaction aborts, etc.

OutOfRange

Operation was attempted past the valid range. E.g., seeking or reading past end of file.

Unimplemented

Operation is not implemented or not supported/enabled in this service.

Internal

Internal errors. Means some invariants expected by underlying system has been broken. If you see one of these errors, something is very broken.

Unavailable

The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.

DataLoss

Unrecoverable data loss or corruption.
