Types

type EtcdError

type EtcdError struct {
	// contains filtered or unexported fields
}

EtcdError defines gRPC server errors. (https://github.com/grpc/grpc-go/blob/master/rpc_util.go#L319-L323)

func (EtcdError) Code

func (e EtcdError) Code() codes.Code

Code returns grpc/codes.Code. TODO: define clientv3/codes.Code.

func (EtcdError) Error

func (e EtcdError) Error() string
