Struct DispatchPolicyVerdict 

pub struct DispatchPolicyVerdict {
    pub persistent: PersistentKernelDecision,
    pub arm_independence: ArmIndependenceVerdict,
    pub copy_overlap: Option<CopyOverlapDecision>,
    pub command_reuse: CommandReuseDecision,
    pub bindless: BindlessDecision,
    pub trace_jit: TraceJitDecision,
}

Result bundle from a single dispatch-policy invocation. Every sub-substrate verdict appears in its typed form.

Fields

persistent: PersistentKernelDecision

D1 persistent-kernel verdict.

arm_independence: ArmIndependenceVerdict

D2 arm-independence verdict for the (arm_a, arm_b) pair.

copy_overlap: Option<CopyOverlapDecision>

None when the inputs had no copy_dst_slot; otherwise the D3 substrate’s verdict for that copy.

command_reuse: CommandReuseDecision

D4 command-reuse verdict.

bindless: BindlessDecision

D9 bindless verdict.

trace_jit: TraceJitDecision

I2 trace-JIT speculation verdict.

Implementations

impl DispatchPolicyVerdict

pub fn primary_execution_mode(&self) -> DispatchExecutionMode

Return the mutually exclusive primary launch strategy.

D1 persistent kernels and D4 command reuse can both be profitable on paper. A concrete dispatcher cannot run both for the same launch group, so this resolver chooses the higher predicted savings. Equal savings prefer command reuse because it avoids persistent queue residency.

Trait Implementations

impl Clone for DispatchPolicyVerdict

fn clone(&self) -> DispatchPolicyVerdict

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DispatchPolicyVerdict

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

Formats the value using the given formatter.
