Struct wgpu_types::PresentationTimestamp
source · pub struct PresentationTimestamp(pub u128);
Expand description
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§
source§impl PresentationTimestamp
impl PresentationTimestamp
sourcepub const INVALID_TIMESTAMP: Self = _
pub const INVALID_TIMESTAMP: Self = _
A timestamp that is invalid due to the platform not having a timestamp system.
sourcepub fn is_invalid(self) -> bool
pub fn is_invalid(self) -> bool
Returns true if this timestamp is the invalid timestamp.
