Functions

func Code

func Code(err error) int

Code returns http status code for err. In case of joined errors it returns the first code found in the chain.

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.
