Enum PerfClock

#[repr(i32)]
pub enum PerfClock {
    UnknownPerfClock = 0,
    Realtime = 1,
    Monotonic = 2,
    MonotonicRaw = 3,
    Boottime = 4,
}

Subset of clocks that is supported by perf timestamping. CLOCK_TAI is excluded since it’s not expected to be used in practice, but would require additions to the trace clock synchronisation logic.

Variants

UnknownPerfClock = 0

Realtime = 1

Monotonic = 2

MonotonicRaw = 3

Boottime = 4

Implementations

impl PerfClock

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of PerfClock.

pub fn from_i32(value: i32) -> Option<PerfClock>

Converts an i32 to a PerfClock, or None if value is not a valid variant.

impl PerfClock

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

Trait Implementations

impl Clone for PerfClock

fn clone(&self) -> PerfClock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PerfClock

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

Formats the value using the given formatter.

impl Default for PerfClock

fn default() -> PerfClock

Returns the “default value” for a type.

impl From<PerfClock> for i32

fn from(value: PerfClock) -> i32

Converts to this type from the input type.

impl Hash for PerfClock

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 Ord for PerfClock

fn cmp(&self, other: &PerfClock) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PerfClock

fn eq(&self, other: &PerfClock) -> 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 PartialOrd for PerfClock

fn partial_cmp(&self, other: &PerfClock) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
