Go Validate

A suite of straightforward validation functions. You put something in, you get back nil or an error.

Error handling

You can use errors.Is() to ascertain the type of errors thrown by validation functions. This may be helpful to control side effects, particularly if using multiple validators and returning early (similar to a strongly-typed try-catch). For example:

Example

package main

import (
	"errors"
	"fmt"

	"github.com/annybs/go/validate"
)

func main() {
	v := validate.Equal("a")
	if err := v("b"); err != nil {
		if errors.Is(err, validate.ErrNotEqual) {
			fmt.Println("failed successfully")
		} else {
			fmt.Println("failed unsuccessfully")
		}
	}
}
