Functions

func Marshal

func Marshal(v interface{}, fields ...string) ([]byte, error)

Marshal is compatible with std json.Marshal. If fields is nil it acts as the std json package. If fields is not nil it will only return the provided fields.

Example

package main

import (
	"github.com/mnhkahn/jsonfield"
)

type A struct {
	A int
	B int
}

func main() {
	jj := new(A)
	jj.A, jj.B = 111, 222
	byts, err := jsonfield.Marshal(jj, "A") // {"A":111}
	_, _ = byts, err
}
