Function IsDayjs

IsDayjs(
options?: { allow_invalid?: boolean } & ValidationOptions,
): PropertyDecorator

Note that dayjs is not a constructor, so you can't simply use @IsInstance(dayjs).

Example
```
// Ensure the value is a Dayjs object.
@IsDayjs()
dateOfBirth: Dayjs
```
Parameters
- Optionaloptions: { allow_invalid?: boolean } & ValidationOptions
  Accepts the following options (in addition to generic class-validator options):
  
  allow_invalid: boolean = false If true, allow the Dayjs object to be invalid (see isValid()).
