Struct LinuxTime 

pub struct LinuxTime;

Available on crate feature linux only.

🐧 🕘 A configurable family of Linux clocks.

---

^{📍 sys/os/linux/thread}

---

Each LinuxClock selects a concrete Linux timeline and exposes it through the common TimeSourceCfg<u64> interface using nanosecond values.

Trait Implementations

impl Debug for LinuxTime

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

Formats the value using the given formatter.

impl TimeSourceCfg<u64> for LinuxTime

Configurable u64 projection of LinuxTime in nanoseconds.

This is the canonical configurable wide numeric projection for Linux clocks. At nanosecond resolution, u64 spans about 584 years.

Whether the selected timeline is monotonic or absolute depends on the chosen LinuxClock.

type Config = LinuxClock

Runtime configuration used to select a concrete timeline.

fn time_is_monotonic(clock: LinuxClock) -> bool

Returns whether the selected source timeline is monotonic.

fn time_is_absolute(clock: LinuxClock) -> bool

Returns whether the selected source timeline is absolute.

fn time_scale(_: LinuxClock) -> TimeScale

Returns the unit used by time_point_value and time_elapsed_value.

fn time_now(clock: LinuxClock) -> u64

Returns the current time point for the selected configuration.

fn time_point_value(_: LinuxClock, point: u64) -> u64

Converts a time point into a u64 value in time_scale(cfg) units.

fn time_elapsed_value(_: LinuxClock, elapsed: u64) -> u64

Converts an elapsed value into a u64 value in time_scale(cfg) units.

fn time_now_value(cfg: Self::Config) -> u64

Returns the current time as a u64 value in time_scale units.

fn time_elapsed_since(cfg: Self::Config, point: P) -> P::Elapsed

Returns the forward elapsed value from point to now.

fn time_elapsed_since_checked(cfg: Self::Config, point: P) -> Option<P::Elapsed>

Returns the forward elapsed value from point to now, or None if it is not valid or not representable.

fn time_elapsed_since_value(cfg: Self::Config, point: P) -> u64

Returns the forward elapsed value from point to now as a u64 in time_scale units.

fn time_point_seconds(cfg: Self::Config, point: P) -> u64

Converts point to seconds.

fn time_point_millis(cfg: Self::Config, point: P) -> u64

Converts point to milliseconds.

fn time_point_micros(cfg: Self::Config, point: P) -> u64

Converts point to microseconds.

fn time_point_nanos(cfg: Self::Config, point: P) -> u64

Converts point to nanoseconds.

fn time_elapsed_seconds(cfg: Self::Config, elapsed: P::Elapsed) -> u64

Converts elapsed to seconds.

fn time_elapsed_millis(cfg: Self::Config, elapsed: P::Elapsed) -> u64

Converts elapsed to milliseconds.

fn time_elapsed_micros(cfg: Self::Config, elapsed: P::Elapsed) -> u64

Converts elapsed to microseconds.

fn time_elapsed_nanos(cfg: Self::Config, elapsed: P::Elapsed) -> u64

Converts elapsed to nanoseconds.

fn time_now_seconds(cfg: Self::Config) -> u64

Returns the current timestamp in seconds.

fn time_now_millis(cfg: Self::Config) -> u64

Returns the current timestamp in milliseconds.

fn time_now_micros(cfg: Self::Config) -> u64

Returns the current timestamp in microseconds.

fn time_now_nanos(cfg: Self::Config) -> u64

Returns the current timestamp in nanoseconds.

fn time_now_millis_f64(cfg: Self::Config) -> f64

Returns the current timestamp as milliseconds in f64.
