Generic indexed tensor movement required by bounded grouped execution.

Implementations expose integer-index discovery and tensor movement without receiving architecture plans, bank meaning, or text lifecycle policy.

Required Associated Types

type Error

Indexed movement failure.

Required Methods

fn index_demands( &mut self, indices: &B::Tensor, upper_bound: usize, context: &<B::Tensor as Tensor>::Context, ) -> Result<Vec<(usize, u64)>, Self::Error>

Returns deterministic demand counts for integer indices below upper_bound.

fn remap_indices( &mut self, indices: &B::Tensor, mapping: &[(usize, usize)], context: &<B::Tensor as Tensor>::Context, ) -> Result<B::Tensor, Self::Error>

Rewrites source indices through one exact source-to-compact mapping.

fn select_rows( &mut self, value: &B::Tensor, start: usize, end: usize, context: &<B::Tensor as Tensor>::Context, ) -> Result<B::Tensor, Self::Error>

Selects a contiguous range along the leading row axis.

fn concatenate_rows( &mut self, values: &[B::Tensor], context: &<B::Tensor as Tensor>::Context, ) -> Result<B::Tensor, Self::Error>

Concatenates row partitions in their original order.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
