Struct rerun::external::eframe::egui_wgpu::wgpu::PresentationTimestamp

pub struct PresentationTimestamp(pub u128);

Nanosecond timestamp used by the presentation engine.

The specific clock depends on the window system integration (WSI) API used.

WSI	Clock
IDXGISwapchain	QueryPerformanceCounter
IPresentationManager	QueryInterruptTimePrecise
CAMetalLayer	mach_absolute_time
VK_GOOGLE_display_timing	clock_gettime(CLOCK_MONOTONIC)

Tuple Fields

0: u128

Timestamp in nanoseconds.

Implementations

impl PresentationTimestamp

pub const INVALID_TIMESTAMP: PresentationTimestamp = _

A timestamp that is invalid due to the platform not having a timestamp system.

pub fn is_invalid(self) -> bool

Returns true if this timestamp is the invalid timestamp.

Trait Implementations

impl Clone for PresentationTimestamp

fn clone(&self) -> PresentationTimestamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PresentationTimestamp

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

Formats the value using the given formatter.

impl Ord for PresentationTimestamp

fn cmp(&self, other: &PresentationTimestamp) -> 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 PresentationTimestamp

fn eq(&self, other: &PresentationTimestamp) -> 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 PresentationTimestamp

fn partial_cmp(&self, other: &PresentationTimestamp) -> 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.
