Struct cap_primitives::time::SystemClock

pub struct SystemClock(_);

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

impl SystemClock

pub const UNIX_EPOCH: SystemTime

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.

pub const unsafe fn new() -> Self

Constructs a new instance of Self.

Safety

This is unsafe because access to clocks is an ambient authority.

pub fn now(&self) -> SystemTime

Returns an instant corresponding to “now”.

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

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.
