Struct TimestampQuery 

pub struct TimestampQuery {
    pub label: String,
    pub begin_ms: f64,
    pub end_ms: f64,
}

A timestamp query pair (begin, end) for a named pass.

On a real GPU this maps to VkQueryPool or wgpu::QuerySet writes at the start and end of a render/compute pass. Here we store wall-clock f64 timestamps in milliseconds.

Fields

label: String

Human-readable label for this pass.

begin_ms: f64

Begin timestamp in milliseconds (relative to some epoch).

end_ms: f64

End timestamp in milliseconds.

Implementations

impl TimestampQuery

pub fn new(label: impl Into<String>, begin_ms: f64, end_ms: f64) -> Self

Create a new timestamp query pair.

pub fn elapsed_ms(&self) -> f64

Elapsed duration in milliseconds.

Trait Implementations

fn clone(&self) -> TimestampQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimestampQuery

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

Formats the value using the given formatter.
