Struct Duration 

pub struct Duration(/* private fields */);

The underlying u128 represents the duration in nanoseconds.

Implementations

impl Duration

pub const HOUR: Self

pub const MICROSECOND: Self

pub const MILLISECOND: Self

pub const MINUTE: Self

pub const NANOSECOND: Self

impl Duration

pub const fn from_nanos(ns: u128) -> Self
