Enum TimerSpec 

pub enum TimerSpec {
    Absolute {
        nanos_since_boot: u64,
    },
    Relative {
        nanos: u64,
    },
}

Timer specification for timer_wait.

Timers can be absolute (wait until a specific instant) or relative (wait for a duration from now).

Variants

Absolute

Wait until an absolute instant.

The instant is represented as nanoseconds since kernel boot.

Fields

nanos_since_boot: u64

Nanoseconds since kernel boot.

Relative

Wait for a relative duration.

The duration is represented as nanoseconds.

Fields

nanos: u64

Duration in nanoseconds.

Implementations

impl TimerSpec

pub const fn absolute(nanos_since_boot: u64) -> Self

Creates an absolute timer specification.

pub const fn relative(nanos: u64) -> Self

Creates a relative timer specification.

pub const fn from_millis(millis: u64) -> Self

Creates a relative timer from milliseconds.

pub const fn from_micros(micros: u64) -> Self

Creates a relative timer from microseconds.

pub const fn from_secs(secs: u64) -> Self

Creates a relative timer from seconds.

pub const fn is_absolute(&self) -> bool

Returns true if this is an absolute timer.

pub const fn is_relative(&self) -> bool

Returns true if this is a relative timer.

pub const fn nanos(&self) -> u64

Returns the nanoseconds value.

Trait Implementations

impl Clone for TimerSpec

fn clone(&self) -> TimerSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimerSpec

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

Formats the value using the given formatter.

impl Default for TimerSpec

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TimerSpec

fn eq(&self, other: &TimerSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
