Duration

record

record Duration

Represents a precise span of time.

Durations carry normalized whole seconds and nanoseconds and are used for timer game time. The nanosecond component is always between zero and 999,999,999, including for negative durations.

Examples

Represent an exact delay

let delay = Duration.fromSeconds(2)
