Struct coarsetime::Date

pub struct Date(/* private fields */);

Expand description

A representation of the current, actual date.

Implementations§

impl Date

pub fn now() -> Date

Returns an instant corresponding to “now”

This function also updates the stored instant.

pub fn recent() -> Date

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: Date) -> 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.

pub fn as_ticks(&self) -> u64

Return a representation of this instant as a number of “ticks”.

Note that length of a ‘tick’ is not guaranteed to represent the same amount of time across different platforms, or from one version of coarsetime to another.

Note also that the instant represented by “0” ticks is unspecified. It is not guaranteed to be the same time across different platforms, or from one version of coarsetime to another.

This API is mainly intended for applications that need to store the value of an Date in an AtomicU64.
