Struct HistogramddPlan 

pub struct HistogramddPlan<T: Element> { /* private fields */ }

histogramdd plan (reserved — returns Unsupported).

Status: API stub. select() always returns Unsupported in the trailblazer; use HistogramPlan for 1-D histograms today. This file pins the public surface (Descriptor / Args / Plan struct names) so callers can type-check against the eventual N-D path without churn.

When the real kernel lands: PyTorch torch.histogramdd shape — input [numel, ndim], output flat [prod(num_bins_per_dim)].

Implementations

impl<T: Element> HistogramddPlan<T>

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

Pick a kernel for desc — returns Unsupported in trailblazer.

pub fn workspace_size(&self) -> usize

Workspace size in bytes.

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.

pub fn can_implement(&self, _args: &HistogramddArgs<'_, T>) -> Result<()>

Validate args — always returns Unsupported.

pub fn run( &self, _stream: &Stream, _workspace: Workspace<'_>, _args: HistogramddArgs<'_, T>, ) -> Result<()>

Launch — always returns Unsupported.
