Struct PosixClock

Source 
pub struct PosixClock(/* private fields */);
Expand description

The POSIX clockid_t represents numerous types of clocks (wall, cpu, etc) However, they share a common API

Implementations§

Source§

impl PosixClock

Source

pub unsafe fn from_clockid(clockid: clockid_t) -> PosixClock

Creating a POSIX clock struct could result in undefined behavior if passed an invalid clockid_t It is safe to call this on a known-valid clockid
