Struct wall_clock::WallClockTime

pub struct WallClockTime { /* private fields */ }

A representation of a time, as read from a wall clock, independent of date or time zone.

Implementations

impl WallClockTime

pub const fn new(hours: u8, minutes: u8, seconds: u8) -> Self

A new wall-clock time set to the provided hours, minutes, and seconds.

Panic

Panics if any values are too high for a wall clock (hours >= 24, minutes >= 60, seconds >= 60). Wall clocks don’t know about leap seconds.

pub const fn new_with_micros( hours: u8, minutes: u8, seconds: u8, micros: u32 ) -> Self

A new wall-clock time set to the provided hours, minutes, seconds, and microseconds.

Panic

Panics if any values are too high for a wall clock (hours >= 24, minutes >= 60, seconds >= 60). Wall clocks don’t know about leap seconds.

pub const fn new_midnight_offset(seconds: u32, micros: u32) -> Self

A new wall-clock time corresponding to the number of seconds and microseconds offset from midnight.

Panic

Panics if any values are higher than is valid for a wall clock (seconds >= 86,400; micros >= 1,000,000).

pub const fn hour(&self) -> u8

The number of hours since midnight.

pub const fn minute(&self) -> u8

The number of minutes since the last hour.

pub const fn second(&self) -> u8

The number of seconds since the last minute.

pub const fn microsecond(&self) -> u32

The number of microseconds since the last second.
