[−][src]Struct cap_std::time::SystemTime
A measurement of the system clock, useful for talking to external entities like the file system or other processes.
This corresponds to std::time::SystemTime
.
Note that this SystemTime
has no now
, elapsed
methods. To obtain the
current time or measure the duration to the current time, you must first
obtain a SystemClock
, and then call SystemClock::now
or
SystemClock::elapsed
instead. The UNIX_EPOCH
constant is at
SystemClock::UNIX_EPOCH
.
Similar to the filetime
crate, when
RUSTFLAGS=--cfg emulate_second_only_system
is set, SystemTime
will
round times from the operating system down to the second. This emulates
the behavior of some file systems, mostly
HFS, allowing debugging on other
hardware.
Implementations
impl SystemTime
[src]
pub fn from_std(std: SystemTime) -> SystemTime
[src]
Constructs a new instance of Self
from the given std::time::SystemTime
.
pub const fn into_std(self) -> SystemTime
[src]
Constructs a new instance of std::time::SystemTime
from the given Self
.
pub fn duration_since(
&self,
earlier: SystemTime
) -> Result<Duration, SystemTimeError>
[src]
&self,
earlier: SystemTime
) -> Result<Duration, SystemTimeError>
Returns the amount of time elapsed from another instant to this one.
This corresponds to std::time::SystemTime::duration_since
.
pub fn checked_add(&self, duration: Duration) -> Option<SystemTime>
[src]
Returns Some(t)
where t
is the time self + duration
if t
can be represented as
SystemTime
(which means it's inside the bounds of the underlying data structure), None
otherwise.
This corresponds to std::time::SystemTime::checked_add
.
pub fn checked_sub(&self, duration: Duration) -> Option<SystemTime>
[src]
Returns Some(t)
where t
is the time self - duration
if t
can be represented as
SystemTime
(which means it's inside the bounds of the underlying data structure), None
otherwise.
This corresponds to std::time::SystemTime::checked_sub
.
Trait Implementations
impl Add<Duration> for SystemTime
[src]
type Output = SystemTime
The resulting type after applying the +
operator.
pub fn add(self, dur: Duration) -> SystemTime

Panics
This function may panic if the resulting point in time cannot be represented by the
underlying data structure. See SystemTime::checked_add
for a version without panic.
