Overview ¶
Package status implements errors returned by gRPC. These errors are serialized and transmitted on the wire between server and client, and allow for additional data to be transmitted via the Details field in the status proto. gRPC service handlers should return an error created by this package, and gRPC clients should expect a corresponding error to be returned from the RPC call.
This package upholds the invariants that a non-nil error may not contain an OK code, and an OK code must result in a nil error.

Functions ¶
func Code ¶ added in v1.9.0
Code returns the Code of the error if it is a Status error or if it wraps a Status error. If that is not the case, it returns codes.OK if err is nil, or codes.Unknown otherwise.
func ErrorProto ¶
ErrorProto returns an error representing s. If s.Code is OK, returns nil.
Types ¶
type Status ¶
Status references google.golang.org/grpc/internal/status. It represents an RPC status code, message, and details. It is immutable and should be created with New, Newf, or FromProto. https://godoc.org/google.golang.org/grpc/internal/status
func Convert ¶ added in v1.10.0
Convert is a convenience function which removes the need to handle the boolean return value from FromError.
func FromContextError ¶ added in v1.13.0
FromContextError converts a context error or wrapped context error into a Status. It returns a Status with codes.OK if err is nil, or a Status with codes.Unknown if err is non-nil and not a context error.
func FromError ¶
FromError returns a Status representation of err.
If err was produced by this package or implements the method `GRPCStatus() *Status` and `GRPCStatus()` does not return nil, or if err wraps a type satisfying this, the Status from `GRPCStatus()` is returned. For wrapped errors, the message returned contains the entire err.Error() text and not just the wrapped status. In that case, ok is true.
If err is nil, a Status is returned with codes.OK and no message, and ok is true.
If err implements the method `GRPCStatus() *Status` and `GRPCStatus()` returns nil (which maps to Codes.OK), or if err wraps a type satisfying this, a Status is returned with codes.Unknown and err's Error() message, and ok is false.
Otherwise, err is an error not compatible with this package. In this case, a Status is returned with codes.Unknown and err's Error() message, and ok is false.
