Enum PollStrategy 

pub enum PollStrategy {
    Spin,
    Yield,
    BackoffMicros(u64),
}

Strategy for polling GPU event completion.

Controls the trade-off between CPU usage and latency when waiting for a kernel to finish.

Variants

Spin

Busy-poll event.query() with no pause between polls.

Lowest latency but highest CPU usage.

Yield

Call std::thread::yield_now() between polls.

Allows other threads to run but still polls frequently.

BackoffMicros(u64)

Sleep for the given number of microseconds between polls.

Lower CPU usage at the cost of higher latency.

Trait Implementations

impl Clone for PollStrategy

fn clone(&self) -> PollStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PollStrategy

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

Formats the value using the given formatter.

impl Default for PollStrategy

fn default() -> Self

Defaults to Yield for a balanced trade-off between latency and CPU usage.

impl PartialEq for PollStrategy

fn eq(&self, other: &PollStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for PollStrategy
