Types

type DontCheckChildrens

type DontCheckChildrens struct{}

DontCheckChildrens a special marker that stops checking child branches

type Tree

type Tree struct {
	Validator Validator
	Data      interface{}
	Result    error
	Valid     bool
	Childrens []Tree
}

Tree describes the validation tree

func (*Tree) CheckChildrens

func (t *Tree) CheckChildrens() bool

CheckChildrens returns a flag - whether it is necessary to perform checks of child branches

func (*Tree) ShowErrors

func (t *Tree) ShowErrors()

ShowErrors display validation errors on the screen

func (*Tree) Validate

func (t *Tree) Validate(params ...interface{})

Validate Recursive function - traverses all branches of the validation tree and calls the validator function. The result of the check is saved in the Valid field.

type Validator

type Validator func(params ...interface{}) (interface{}, error)

Validator describes the validation function
