Enum ClockId 

#[non_exhaustive]
#[repr(i32)]
pub enum ClockId {
    Realtime = 0,
    Monotonic = 1,
    ProcessCPUTime = 2,
    ThreadCPUTime = 3,
    RealtimeCoarse = 5,

}

Available on crate feature time and non-WASI only.

clockid_t CLOCK_* constants for use with clock_gettime.

These constants are always supported at runtime, so clock_gettime never has to fail with INVAL due to an unsupported clock. See DynamicClockId for a greater set of clocks, with the caveat that not all of them are always supported.

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.

Trait Implementations

impl Clone for ClockId

Available on neither Windows nor target_os=espidf and (crate features thread or time) only.

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

Available on neither Windows nor target_os=espidf and (crate features thread or time) only.

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

Formats the value using the given formatter.

impl Hash for ClockId

Available on neither Windows nor target_os=espidf and (crate features thread or time) only.

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

Available on neither Windows nor target_os=espidf and (crate features thread or time) only.

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.

impl TryFrom<i32> for ClockId

Available on neither Windows nor target_os=espidf and (crate features thread or time) and neither apple nor WASI only.

type Error = Errno

The type returned in the event of a conversion error.

fn try_from(value: clockid_t) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ClockId

Available on neither Windows nor target_os=espidf and (crate features thread or time) only.

impl Eq for ClockId

Available on neither Windows nor target_os=espidf and (crate features thread or time) only.

impl StructuralPartialEq for ClockId

Available on neither Windows nor target_os=espidf and (crate features thread or time) only.
