Struct ConcatenatePlan 

pub struct ConcatenatePlan { /* private fields */ }

A compiled multi-input concatenate traversal.

Each input segment is lowered to a prepared strided copy into the corresponding destination window. The per-input collections are inline up to OPERAND_CAP slots (destination plus four inputs), so a bounded concatenate compiles and executes without touching the heap; above that bound they spill gracefully. segment_starts carries one more entry than there are inputs (the input_count + 1 prefix-sum sentinel whose last entry is the destination total), which is why its bound is the same operand cap.

Implementations

impl ConcatenatePlan

pub fn compile( input_dims: &[&[usize]], input_strides: &[&[isize]], dest_dims: &[usize], dest_strides: &[isize], axis: usize, ) -> Result<ConcatenatePlan, StridedError>

Compile a multi-input concatenate plan for fixed input and destination layouts.

pub fn execute<T>( &self, dest: &mut RawStridedMut<'_, T>, inputs: &[RawStridedRef<'_, T>], exec: Exec<'_>, ) -> Result<(), StridedError>

where T: Copy + Send + Sync,

Execute the prepared concatenate traversal.

pub fn execute_uninit<T>( &self, dest: &mut RawStridedMut<'_, MaybeUninit<T>>, inputs: &[RawStridedRef<'_, T>], exec: Exec<'_>, ) -> Result<(), StridedError>

where T: Copy + Send + Sync,

Execute concatenate into storage whose reachable destination elements are uninitialized.
