Trait ftvf::TemporalSample

pub trait TemporalSample: Sized + Clone + PartialOrd + PartialEq {
    // Required methods
    fn time_since(&self, origin: &Self) -> Option<Duration>;
    fn advanced_by(&self, amount: Duration) -> Self;

    // Provided method
    fn advance_by(&mut self, amount: Duration) { ... }
}

A type that represents a particular point in time. You only need to worry about it if you’re implementing your own timing routines.

Required Methods

fn time_since(&self, origin: &Self) -> Option<Duration>

If this TemporalSample is after the given origin, return the Duration that has passed since that point. If this TemporalSample is before the given origin, return None.

fn advanced_by(&self, amount: Duration) -> Self

Return a new TemporalSample that is this much time into the future.

You must have nanosecond precision. If your underlying type does not have nanosecond precision, you must keep track of the residual.

Provided Methods

fn advance_by(&mut self, amount: Duration)

As advanced_by, but mutates self instead of returning a new value. The default implementation just does *self = self.advanced_by(amount).
