Detailed Description

Type Documentation

enum class QtGrpc::SerializationFormat

Contains preset values for setting the protobuf serializer format.

Constant	Value	Description
`QtGrpc::SerializationFormat::Default`	`0`	The default QGrpcSerializationFormat preset. This preset constructs a QProtobufSerializer with an empty content type suffix.
`QtGrpc::SerializationFormat::Protobuf`	`1`	The embedded protobuf QGrpcSerializationFormat preset. This preset constructs a QProtobufSerializer with the `proto` content type suffix.
`QtGrpc::SerializationFormat::Json`	`2`	The embedded JSON QGrpcSerializationFormat preset. This preset constructs a QProtobufJsonSerializer with the `json` content type suffix.

enum class QtGrpc::StatusCode

Channel's status codes.

Constant	Value	Description
`QtGrpc::StatusCode::Ok`	`0`	No error
`QtGrpc::StatusCode::Cancelled`	`1`	The operation was cancelled, typically by the caller.
`QtGrpc::StatusCode::InvalidArgument`	`3`	The client specified an invalid argument,
`QtGrpc::StatusCode::DeadlineExceeded`	`4`	The deadline expired before the operation could complete,
`QtGrpc::StatusCode::NotFound`	`5`	Some requested entity (e.g., file or directory) was not found.
`QtGrpc::StatusCode::AlreadyExists`	`6`	The entity that a client attempted to create (e.g., file or directory) already exists.
`QtGrpc::StatusCode::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.
`QtGrpc::StatusCode::ResourceExhausted`	`8`	Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.
`QtGrpc::StatusCode::FailedPrecondition`	`9`	The operation was rejected because the system is not in a state required for the operation's execution.
`QtGrpc::StatusCode::Aborted`	`10`	The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.
`QtGrpc::StatusCode::OutOfRange`	`11`	The operation was attempted past the valid range.
`QtGrpc::StatusCode::Unimplemented`	`12`	The operation is not implemented or is not supported/enabled in this service.
`QtGrpc::StatusCode::Internal`	`13`	This means that some invariants expected by the underlying system have been broken.
`QtGrpc::StatusCode::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.
`QtGrpc::StatusCode::DataLoss`	`15`	Unrecoverable data loss or corruption.
`QtGrpc::StatusCode::Unauthenticated`	`16`	The request does not have valid authentication credentials for the operation.
