type Validator

type Validator struct {
	FieldErrors    map[string]string
	NonFieldErrors []string
}

func (*Validator) AddFieldError

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

AddFieldError adds an error message for a specific field to the FieldErrors map.

func (*Validator) AddNonFieldError

func (v *Validator) AddNonFieldError(message string)

func (*Validator) CheckField

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

CheckField checks a condition. If that fails, it adds an error message to the FieldErrors map.

func (*Validator) IsValid

func (v *Validator) IsValid() bool

IsValid returns true if there are no errors, otherwise false.
