Functions

func Code

func Code(err error) int

Code returns http status code for err.

Example

package main

import (
	"errors"
	"fmt"
	"net/http"

	"github.com/hedhyw/semerr/pkg/v1/httperr"
	"github.com/hedhyw/semerr/pkg/v1/semerr"
)

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

	fmt.Println(
		"Is err bad request?",
		httperr.Code(err) == http.StatusBadRequest,
	)
}

Output:

Is err bad request? true

func Wrap

func Wrap(err error, code int) 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.
