Struct ScanPlan 

pub struct ScanPlan<T: Element, const N: usize> { /* private fields */ }

Single-axis scan forward plan — see the module-level docs for formulas, dtypes, workspace, and precision guarantees.

T: Element is the element type (f32 / f64 / f16 / bf16). const N: usize is the tensor rank (1..=8).

Implementations

impl<T: Element, const N: usize> ScanPlan<T, N>

pub fn select( _stream: &Stream, desc: &ScanDescriptor<N>, _pref: PlanPreference, ) -> Result<Self>

Pick a kernel for desc. Validates scan_axis < N, the dtype is in the wired FP family, and tensor rank ≤ 8. Returns Error::Unsupported for cells outside the wired matrix.

pub fn can_implement(&self, args: &ScanArgs<'_, T, N>) -> Result<()>

Validate args.

pub fn workspace_size(&self) -> usize

Workspace size in bytes. Always zero.

pub fn sku(&self) -> KernelSku

Identity of the kernel this plan picked.

pub fn precision_guarantee(&self) -> PrecisionGuarantee

Numerical guarantees for this plan’s kernel — deterministic, bit-stable on the same hardware, f32 accumulator for f16 / bf16 inputs (FP detour).

pub fn run( &self, stream: &Stream, _workspace: Workspace<'_>, args: ScanArgs<'_, T, N>, ) -> Result<()>

Launch the kernel against args. Calls can_implement first; returns Ok(()) for empty tensors.
