Enum clockid

#[non_exhaustive]
#[repr(u32)]
pub enum clockid {
    MONOTONIC = 1,
    PROCESS_CPUTIME_ID = 2,
    REALTIME = 3,
    THREAD_CPUTIME_ID = 4,
}

Identifiers for clocks.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MONOTONIC = 1

The system-wide monotonic clock, which is defined as a clock measuring real time, whose value cannot be adjusted and which cannot have negative clock jumps.

The epoch of this clock is undefined. The absolute time value of this clock therefore has no meaning.

PROCESS_CPUTIME_ID = 2

The CPU-time clock associated with the current process.

REALTIME = 3

The system-wide clock measuring real time. Time value zero corresponds with 1970-01-01T00:00:00Z.

THREAD_CPUTIME_ID = 4

The CPU-time clock associated with the current thread.

Trait Implementations

impl Clone for clockid

fn clone(&self) -> clockid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for clockid

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

Formats the value using the given formatter.

impl Hash for clockid

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for clockid

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