Struct coarsetime::Instant

pub struct Instant(_);

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

Implementations

impl Instant

pub fn now() -> Instant

Returns an instant corresponding to "now"

This function also updates the stored instant.

pub fn recent() -> Instant

Returns an instant corresponding to the latest update

pub fn update()

Update the stored instant

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

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

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

pub fn elapsed_since_recent(&self) -> Duration

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

pub fn elapsed(&self) -> Duration

Returns the amount of time elapsed since this instant was created

This function also updates the stored instant.
