Functions

func Code

func Code(err error) codes.Code

Code returns grpc status code for err.

Example

package main

import (
	"errors"
	"fmt"

	"github.com/hedhyw/semerr/pkg/v1/grpcerr"
	"github.com/hedhyw/semerr/pkg/v1/semerr"

	"google.golang.org/grpc/codes"
)

func main() {
	err := semerr.NewBadRequestError(errors.New("bad request error"))

	fmt.Println(
		"Is err invalid argument?",
		grpcerr.Code(err) == codes.InvalidArgument,
	)
}

Output:

Is err invalid argument? true

func Wrap

func Wrap(err error, code codes.Code) error

Wrap wraps the `err` with an error corresponding to the `code`. If there is no `err` for this code then the `err` will be returned without wrapping.
