Functions

func WrapGRPCErrorWithContextError

func WrapGRPCErrorWithContextError(ctx context.Context, err error) error

WrapGRPCErrorWithContextError checks if the given error is a gRPC error corresponding to a standard golang context error, and if it is, wraps the former with the latter. If the given error isn't a gRPC error, or it doesn't correspond to a standard golang context error, the original error is returned.

Types

type ErrorWithStatus

type ErrorWithStatus struct {
	UnderlyingErr error
	Status        *status.Status
	// contains filtered or unexported fields
}

ErrorWithStatus is used for wrapping errors returned by ingester. Errors returned by ingester should be gRPC errors, but the errors produced by both gogo/status and grpc/status packages do not keep the semantics of the underlying error, which is sometimes needed. For example, the logging middleware needs to know whether an error should be logged, sampled or ignored. Errors of type ErrorWithStatus are valid gRPC errors that could be parsed by both gogo/status and grpc/status packages, but which preserve the original error semantics.

func WrapErrorWithGRPCStatus

func WrapErrorWithGRPCStatus(originalErr error, errCode codes.Code, errDetails *mimirpb.ErrorDetails) ErrorWithStatus

WrapErrorWithGRPCStatus wraps the given error with a gRPC status, which is built out of the given parameters: the gRPC status' code and details are passed as parameters, while its message corresponds to the original error. The resulting error is of type ErrorWithStatus.

func (ErrorWithStatus) Equals

func (e ErrorWithStatus) Equals(err error) bool

Equals returns true if the given error and this error are equal, i.e., if they are both of type ErrorWithStatus, if their underlying statuses have the same code, messages, and if both have either no details, or exactly one detail of type mimirpb.ErrorDetails, which are equal too.

func (ErrorWithStatus) Err

func (e ErrorWithStatus) Err() error

Err returns an immutable error representing this ErrorWithStatus. Returns nil if UnderlyingError is nil or Status.Code() is OK. The resulting error is of type error, and it can be parsed to the corresponding gRPC status by both gogo/status and grpc/status packages.

func (ErrorWithStatus) Error

func (e ErrorWithStatus) Error() string

func (ErrorWithStatus) GRPCStatus

func (e ErrorWithStatus) GRPCStatus() *grpcstatus.Status

GRPCStatus with a *grpcstatus.Status as output is needed for a correct execution of grpc/status.FromError().

func (ErrorWithStatus) Unwrap

func (e ErrorWithStatus) Unwrap() []error
