Function ExclusiveMinimum

dsl/validation.go:199–229

ExclusiveMinimum adds a "exclusiveMinimum" validation to the attribute. See http://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.6.2.5. Example: Attribute("float", float32, func() { ExclusiveMinimum(100) })

(val any)

//	    ExclusiveMinimum(100)
//	})
func ExclusiveMinimum(val any) {
	if a, ok := eval.Current().(*expr.AttributeExpr); ok {
		if a.Type != nil &&
			a.Type.Kind() != expr.IntKind && a.Type.Kind() != expr.UIntKind &&
			a.Type.Kind() != expr.Int32Kind && a.Type.Kind() != expr.UInt32Kind &&
			a.Type.Kind() != expr.Int64Kind && a.Type.Kind() != expr.UInt64Kind &&
			a.Type.Kind() != expr.Float32Kind && a.Type.Kind() != expr.Float64Kind {
			incompatibleAttributeType("exclusiveMinimum", a.Type.Name(), "a number")
		} else {
			var f float64
			switch v := val.(type) {
			case float32, float64, int, int8, int16, int32, int64, uint8, uint16, uint32, uint64:
				f = reflect.ValueOf(v).Convert(reflect.TypeOf(float64(0.0))).Float()
			case string:
				var err error
				f, err = strconv.ParseFloat(v, 64)
				if err != nil {
					eval.ReportError("invalid number value %#v", v)
					return
				}
			default:
				eval.ReportError("invalid number value %#v", v)
				return
			}
			if a.Validation == nil {
				a.Validation = &expr.ValidationExpr{}
			}
			a.Validation.ExclusiveMinimum = &f
		}
	}
