Enum tikv_util::time::Instant

pub enum Instant {
    Monotonic(Timespec),
    MonotonicCoarse(Timespec),
}

A measurement of a monotonically increasing clock. It’s similar and meant to replace std::time::Instant, for providing extra features.

Variants

Monotonic(Timespec)

MonotonicCoarse(Timespec)

Implementations

impl Instant

pub fn now() -> Instant

pub fn now_coarse() -> Instant

pub fn elapsed(&self) -> Duration

pub fn elapsed_secs(&self) -> f64

pub fn duration_since(&self, earlier: Instant) -> Duration

pub fn checked_sub(&self, other: Instant) -> Option<Duration>

It is similar to duration_since, but it won’t panic when self is less than other, and None will be returned in this case.

Callers need to ensure that self and other are same type of Instants.

pub fn elapsed_duration(later: Timespec, earlier: Timespec) -> Duration

fn elapsed_duration_coarse(later: Timespec, earlier: Timespec) -> Duration
