[−][src]Struct cap_std::time::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
[src]
pub const UNIX_EPOCH: SystemTime
[src]
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 unsafe fn new() -> SystemClock
[src]
Constructs a new instance of Self
.
Safety
This is unsafe because access to clocks is an ambient authority.
pub fn now(&self) -> SystemTime
[src]
Returns an instant corresponding to "now".
This corresponds to SystemTime::now
.
pub fn elapsed(
&self,
system_time: SystemTime
) -> Result<Duration, SystemTimeError>
[src]
&self,
system_time: SystemTime
) -> Result<Duration, SystemTimeError>
Returns the amount of time elapsed since this instant was created.
This corresponds to SystemTime::elapsed
.
