Crate ndslice

Expand description

Core mesh components for the hyperactor framework.

Provides Slice, a compact representation of a subset of a multidimensional array. See Slice for more details.

This crate defines the foundational abstractions used in hyperactor’s mesh layer, including multidimensional shapes and selection algebra. The crate avoids dependencies on procedural macros and other higher-level constructs, enabling reuse in both runtime and macro contexts.

Modules§

reshape: Reshaping transformations for multidimensional slices and shapes. Dimensional reshaping of slices and shapes.
selection: Selection algebra for describing multidimensional mesh regions. This module defines a recursive algebra for selecting coordinates in a multidimensional space.
shape: Core types for representing multidimensional shapes and strides.
utils: Utilities.
view: Types to describe extents, points and views.

Macros§

assert_round_trip
assert_structurally_eq
extent: Construct a new extent with the given set of dimension-size pairs.
sel_from_shape: Construct a Selection from a Shape using labeled dimension constraints.
select: Perform a sub-selection on the provided Shape object.
shape: Construct a new shape with the given set of dimension-size pairs in row-major order.

Structs§

DimSliceIterator: Iterates over the Cartesian product of a list of dimension sizes.
Slice: Slice is a compact representation of indices into the flat representation of an n-dimensional array. Given an offset, sizes of each dimension, and strides for each dimension, Slice can compute indices into the flat array.
