Struct coarsetime::Instant

pub struct Instant(_);

A measurement of a monotonically increasing clock. Opaque and useful only with Duration.

Methods

impl Instant

fn now() -> Instant

Returns an instant corresponding to "now"

This function also updates the stored instant.

fn recent() -> Instant

Returns an instant corresponding to the latest update

fn update()

Update the stored instant

This function should be called frequently, for example in an event loop or using an Updater task.

fn duration_since(&self, earlier: Instant) -> Duration

Returns the amount of time elapsed from another instant to this one

fn elapsed_since_recent(&self) -> Duration

Returns the amount of time elapsed between the this instant was created and the latest update

fn elapsed(&self) -> Duration

Returns the amount of time elapsed since this instant was created

This function also updates the stored instant.
