Function IsDuration

IsDuration(options?): PropertyDecorator
Checks if the given value is a valid Dayjs duration.

A duration is considered valid if and only if:
- it passes dayjs.isDuration()
- its numeric value is a finite number (i.e., duration.asMilliseconds() is not NaN)
This requires the duration-plugin to be loaded. If this is not the case, an error will be thrown.

Example
```
// Ensure the value is a Dayjs duration.
@IsDuration()
value: Duration
```
Parameters
- Optional options: {
  allow_invalid?: boolean;
  } & ValidationOptions
  Accepts the following options (in addition to generic class-validator options):
  - allow_invalid: boolean = false If true, allow the duration to be invalid.
Returns PropertyDecorator
