Function IsDuration

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
