Struct PersistentKernelInputs 

pub struct PersistentKernelInputs {
    pub batch_size: u32,
    pub per_launch_overhead_ns: u64,
    pub per_item_kernel_ns: u64,
    pub persistent_setup_overhead_ns: u64,
}

Inputs to the persistent-kernel decision.

Fields

batch_size: u32

Number of small launches in the upcoming batch.

per_launch_overhead_ns: u64

Average per-launch host-side overhead in nanoseconds. Measured on the live backend at startup; native is typically ~5_000 ns, portable typically ~25_000 ns.

per_item_kernel_ns: u64

Average per-item kernel duration in nanoseconds. The dispatcher measures this on the warmup pass before the batch.

persistent_setup_overhead_ns: u64

Setup cost of bringing up persistent mode (work-queue alloc, initial launch, signal handshake) in nanoseconds. native: ~50_000 for a fresh queue; portable: ~200_000.

Trait Implementations

impl Clone for PersistentKernelInputs

fn clone(&self) -> PersistentKernelInputs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PersistentKernelInputs

impl Debug for PersistentKernelInputs

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

Formats the value using the given formatter.

impl Eq for PersistentKernelInputs

impl PartialEq for PersistentKernelInputs

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