Struct Instant 

pub struct Instant<'a, R: Rate>(/* private fields */);

A point in the tick count.

Comparable and subtractable, and bounded to the Timer it came from: a count that stopped and started again would leave it meaning nothing.

Implementations

impl<R: Rate> Instant<'_, R>

pub fn elapsed(self) -> Duration<R>

How long since this was taken.

pub fn saturating_duration_since(self, earlier: Self) -> Duration<R>

How long from earlier to this.

Zero if earlier is the later of the two.

pub fn checked_duration_since(self, earlier: Self) -> Option<Duration<R>>

How long from earlier to this, or None if earlier is the later.
