Struct Timer 

pub struct Timer<'g> { /* private fields */ }

用一对 CUDA 事件量设备上一段工作的耗时（只算 GPU 执行，不含主机侧开销）。

Implementations

impl Timer<'_>

pub fn stop_ms(&self) -> Result<f32, String>

记下终点，等它完成，返回起点到终点的毫秒数。

fn gpu_ms(g: &Gpu, reps: usize, mut f: impl FnMut()) -> f64 {
    f();
    g.synchronize().unwrap();
    let t = g.timer().unwrap();
    for _ in 0..reps {
        f();
    }
    t.stop_ms().unwrap() as f64 / reps as f64
}

Trait Implementations

impl Drop for Timer<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
