Struct GpuTimestamp 

pub struct GpuTimestamp {
    pub start_ns: u64,
    pub end_ns: u64,
}

GPU hardware timestamp pair (start / end), feature-gated to wgpu-backend.

In production use, these values are read back from a wgpu::QuerySet of type Timestamp after the GPU has signalled completion. The raw values are in nanoseconds (after scaling by the adapter’s timestamp period).

Fields

start_ns: u64

Raw GPU timestamp at the start of the pass (nanoseconds).

end_ns: u64

Raw GPU timestamp at the end of the pass (nanoseconds).

Implementations

impl GpuTimestamp

pub fn new(start_ns: u64, end_ns: u64) -> Self

Create a new GPU timestamp pair.

pub fn elapsed_ns(&self) -> u64

Elapsed GPU time in nanoseconds (saturating subtraction).

pub fn elapsed_ms(&self) -> f64

Elapsed GPU time in milliseconds.
