Enum ClockSource 

pub enum ClockSource {
    Monotonic,
    Boottime,
    MonotonicRaw,
}

Kernel clock backing stall-threshold accounting.

Wire-format and observer semantics are unchanged; only the kernel clock that drives “now_ns” is configurable.

Variants

Monotonic

CLOCK_MONOTONIC — pauses on system suspend. SRE default, available on every supported platform.

Boottime

CLOCK_BOOTTIME (Linux only) — advances through suspend. Medical / embedded deployment.

MonotonicRaw

CLOCK_MONOTONIC_RAW (macOS / iOS only) — backed by mach_continuous_time; advances through sleep. Darwin equivalent of Linux’s Boottime. Rejected at startup on non-Darwin targets.

Implementations

impl ClockSource

Numeric tag used by the self-watchdog static CLOCK_SOURCE: AtomicU8 in main.rs to communicate the chosen source to the background watchdog thread without an Arc.

pub fn as_u8(self) -> u8

0 → Monotonic, 1 → Boottime, 2 → MonotonicRaw. Stable across versions; only ever produced by as_u8 on the same enum.

pub fn from_u8(byte: u8) -> Self

Inverse of Self::as_u8; unknown values fall back to Monotonic (defensive — the only writer is as_u8 on the same enum).

pub fn clk_id(self) -> Option<i32>

Kernel clk_id argument for clock_gettime(2).

Returns None when the source is unsupported on the current platform (e.g. Boottime on macOS, MonotonicRaw on Linux/BSD).

Trait Implementations

impl Clone for ClockSource

fn clone(&self) -> ClockSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClockSource

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

Formats the value using the given formatter.

impl Default for ClockSource

fn default() -> ClockSource

Returns the “default value” for a type.

impl Display for ClockSource

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

Formats the value using the given formatter.

impl FromStr for ClockSource

type Err = ClockSourceParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for ClockSource

fn eq(&self, other: &ClockSource) -> 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.
