pub struct SystemTime { /* private fields */ }
Expand description

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.

This SystemTime has no now, elapsed methods. To obtain the current time or measure the duration to the current time, 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

Constructs a new instance of Self from the given std::time::SystemTime.

Constructs a new instance of std::time::SystemTime from the given Self.

Returns the amount of time elapsed from another instant to this one.

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

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.

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.

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.
