Struct cap_std::time::SystemClock

source ·
pub struct SystemClock(_);
Expand description

A reference to a system clock, useful for talking to external entities like the file system or other processes.

This does not directly correspond to anything in std, however its methods correspond to methods in std::time::SystemTime.

Implementations§

source§

impl SystemClock

source

pub const UNIX_EPOCH: SystemTime = SystemTime{ std: time::SystemTime::UNIX_EPOCH,}

An anchor in time which can be used to create new SystemTime instances or learn about where in time a SystemTime lies.

This corresponds to std::time::SystemTime::UNIX_EPOCH.

source

pub const fn new(_: AmbientAuthority) -> SystemClock

Constructs a new instance of Self.

Ambient Authority

This uses ambient authority to accesses clocks.

source

pub fn now(&self) -> SystemTime

Returns an instant corresponding to “now”.

This corresponds to std::time::SystemTime::now.

source

pub fn elapsed(
    &self,
    system_time: SystemTime
) -> Result<Duration, SystemTimeError>

Returns the amount of time elapsed since this instant was created.

This corresponds to std::time::SystemTime::elapsed.
