Struct SegmentMinPlan 

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

segment_min plan (sorted, FW only).

out[s, d] = min_{n : segment_ids[n] == s} input[n, d]. Sorted segment-min mirror of SegmentMaxPlan.

When to use: forward sorted segment-min. No BW plan — argmin tracking deferred.

Dtypes: {f32, f64}.

Shape limits: input [N, D]; segment_ids [N]; output [num_segments, D].

Workspace: none.

Precision guarantee: deterministic, bit-stable.

Index policy: out-of-range IDs dropped. Empty segments emit the per-op identity sentinel.

Implementations

impl<T: Element> SegmentMinPlan<T>

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

Pick a kernel.

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

Validate args.

pub fn workspace_size(&self) -> usize

Workspace size — zero.

pub fn sku(&self) -> KernelSku

Identity of the kernel.

pub fn precision_guarantee(&self) -> PrecisionGuarantee

Numerical guarantees.

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

Launch.
