Method StructCtx

validator_instance.go:355–383

StructCtx validates a structs exposed fields, and automatically validates nested structs, unless otherwise specified and also allows passing of context.Context for contextual validation information. It returns InvalidValidationError for bad values passed in and nil or ValidationErrors as error othe

(ctx context.Context, s interface{})

// It returns InvalidValidationError for bad values passed in and nil or ValidationErrors as error otherwise.
// You will need to assert the error if it's not nil eg. err.(validator.ValidationErrors) to access the array of errors.
func (v *Validate) StructCtx(ctx context.Context, s interface{}) (err error) {
	val := reflect.ValueOf(s)
	top := val

	if val.Kind() == reflect.Ptr && !val.IsNil() {
		val = val.Elem()
	}

	if val.Kind() != reflect.Struct || val.Type().ConvertibleTo(timeType) {
		return &InvalidValidationError{Type: reflect.TypeOf(s)}
	}

	// good to validate
	vd := v.pool.Get().(*validate)
	vd.top = top
	vd.isPartial = false
	// vd.hasExcludes = false // only need to reset in StructPartial and StructExcept

	vd.validateStruct(ctx, top, val, val.Type(), vd.ns[0:0], vd.actualNs[0:0], nil)

	if len(vd.errs) > 0 {
		err = vd.errs

// StructFiltered validates a structs exposed fields, that pass the FilterFunc check and automatically validates
