Struct slos_helpers::Timer

pub struct Timer {
    pub seconds: u64,
    pub microseconds: u32,
}

A time keeper.

This structure is used by the kernel to keep record of the current time since boot, as well as for timer operations such as delays.

The global kernel timer can be cloned and then incremented, allowing delay operations by then comparing the cloned and incremented timer to the global timer.

Fields

seconds: u64

microseconds: u32

Implementations

impl Timer

pub const fn new() -> Timer

Create a new timer with it’s values set to zero.

pub fn increment(&mut self, microseconds: u32)

Increment the timer by the given number of microseconds.

This operation wraps the internal microseconds value, keeping the internal seconds value accurate.

pub fn increment_ms(&mut self, milliseconds: u32)

Increment the timer by the given number of milliseconds.

This operation wraps the internal microseconds value, keeping the internal seconds value accurate.

pub fn in_milliseconds(&self) -> u64

Returns this timer’s total time in milliseconds.

Trait Implementations

impl Clone for Timer

fn clone(&self) -> Timer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Timer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Timer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Ord for Timer

fn cmp(&self, other: &Timer) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self
