Enum PersistentKernelDecision 

pub enum PersistentKernelDecision {
    StandardLaunches,
    PersistentKernel {
        savings_ns: u128,
    },
}

Verdict returned by decide_persistent_kernel.

Variants

StandardLaunches

Use the standard launch path - N separate kernel launches. Either the batch is too small to amortise persistent setup, or the per-item kernel is large enough that launch overhead is negligible.

PersistentKernel

Use persistent kernel mode - one launch + device-side queue polling for batch_size work items.

Fields

savings_ns: u128

Predicted total time saved (in nanoseconds) by using the persistent path vs N standard launches. Useful for telemetry and for the autotune store.

Trait Implementations

impl Clone for PersistentKernelDecision

fn clone(&self) -> PersistentKernelDecision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PersistentKernelDecision

impl Debug for PersistentKernelDecision

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

Formats the value using the given formatter.

impl Eq for PersistentKernelDecision

impl PartialEq for PersistentKernelDecision

fn eq(&self, other: &PersistentKernelDecision) -> 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.
