Types

type Validator

type Validator struct {
	Errors      []string       `json:",omitempty"`
	FieldErrors map[string]any `json:",omitempty"`
}

func (*Validator) AddError

func (v *Validator) AddError(message string)

func (*Validator) AddFieldError

func (v *Validator) AddFieldError(key, message string)

func (*Validator) Check

func (v *Validator) Check(ok bool, message string)

func (*Validator) CheckField

func (v *Validator) CheckField(ok bool, key, message string)

func (*Validator) HasErrors

func (v *Validator) HasErrors() bool

HasErrors checks that the Validator struct contains no errors Example:

v := Validator{}
v.Check(foo == 0, "field_name", "error message")
if v.HasErrors() {
	return err
}
