详细描述

In case of error in call/stream processing QGrpcStatus will contain code any of non-Ok QGrpcStatus::StatusCode . This class combines QGrpcStatus::StatusCode and message returned from channel or QGrpc framework.

成员类型文档编制

enum QGrpcStatus:: StatusCode

Channel's status codes.

常量	值	描述
QGrpcStatus::Ok	0	没有错误
QGrpcStatus::Cancelled	1	The operation was cancelled, typically by the caller.
QGrpcStatus::InvalidArgument	3	The client specified an invalid argument,
QGrpcStatus::DeadlineExceeded	4	The deadline expired before the operation could complete,
QGrpcStatus::NotFound	5	Some requested entity (e.g., file or directory) was not found.
QGrpcStatus::AlreadyExists	6	The entity that a client attempted to create (e.g., file or directory) already exists.
QGrpcStatus::PermissionDenied	7	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). This error code does not imply the request is valid or the requested entity exists or satisfies other pre-conditions.
QGrpcStatus::ResourceExhausted	8	Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.
QGrpcStatus::FailedPrecondition	9	The operation was rejected because the system is not in a state required for the operation's execution.
QGrpcStatus::Aborted	10	The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
QGrpcStatus::OutOfRange	11	The operation was attempted past the valid range.
QGrpcStatus::Unimplemented	12	The operation is not implemented or is not supported/enabled in this service.
QGrpcStatus::Internal	13	This means that some invariants expected by the underlying system have been broken.
QGrpcStatus::Unavailable	14	The service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff. Note that it is not always safe to retry non-idempotent operations.
QGrpcStatus::DataLoss	15	Unrecoverable data loss or corruption.
QGrpcStatus::Unauthenticated	16	The request does not have valid authentication credentials for the operation.
