Struct fxprof_processed_profile::CpuDelta

pub struct CpuDelta { /* private fields */ }

The amount of CPU time between thread samples.

This is used in the Firefox Profiler UI to draw an activity graph per thread.

A thread only runs on one CPU at any time, and can get scheduled off and on the CPU between two samples. The CPU delta is the accumulation of time it was running on the CPU.

Implementations

impl CpuDelta

pub const ZERO: Self = _

A CPU delta of zero.

pub fn from_nanos(nanos: u64) -> Self

Create a CPU delta from integer nanoseconds.

pub fn from_micros(micros: u64) -> Self

Create a CPU delta from integer microseconds.

pub fn from_millis(millis: f64) -> Self

Create a CPU delta from float milliseconds.

pub fn is_zero(&self) -> bool

Whether the CPU delta is zero.

Trait Implementations

impl Clone for CpuDelta

fn clone(&self) -> CpuDelta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CpuDelta

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

Formats the value using the given formatter.

impl From<Duration> for CpuDelta

fn from(duration: Duration) -> Self

Converts to this type from the input type.

impl Hash for CpuDelta

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 CpuDelta

fn cmp(&self, other: &CpuDelta) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CpuDelta

fn eq(&self, other: &CpuDelta) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CpuDelta

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for CpuDelta

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
