Crate strided_view 

Device-agnostic strided view types and metadata operations.

This crate is a Rust port of Julia’s StridedViews.jl, providing strided multidimensional array view types with zero-copy metadata transformations.

Core Types

• StridedView / StridedViewMut: Dynamic-rank strided views over existing data
• StridedArray: Owned strided multidimensional array
• ElementOp trait and implementations (Identity, Conj, Transpose, Adjoint): Type-level element operations applied lazily on access

Metadata Transformations

These operate only on dims/strides/offset and never access the underlying data:

• permute: Reorder dimensions
• transpose_2d, adjoint_2d: 2D matrix transformations
• conj: Compose conjugation operation
• broadcast: Expand size-1 dimensions

Re-exports

pub use view::col_major_strides;

pub use view::row_major_strides;

pub use view::StridedArray;

pub use view::StridedView;

pub use view::StridedViewMut;

Modules

auxiliary

Auxiliary routines ported from StridedViews.jl/src/auxiliary.jl

view

Julia-like dynamic-rank strided view types.

Structs

Adjoint

Adjoint operation: f(x) = adjoint(x) = conj(transpose(x)) For scalar numbers, this is conj.

Conj

Complex conjugate operation: f(x) = conj(x)

ErasedRawStridedMut

Borrowed dtype-erased raw strided output layout.

ErasedRawStridedPtr

Pointer-backed dtype-erased input used by one-shot write entry points.

ErasedRawStridedRef

Borrowed dtype-erased raw strided input layout.

ErasedRawStridedUninitMut

Borrowed dtype-erased raw strided output whose reachable elements may be uninitialized.

Identity

Identity operation: f(x) = x

RawStridedMut

Borrowed raw strided output layout.

RawStridedRef

Borrowed raw strided input layout.

Transpose

Transpose operation: f(x) = transpose(x) For scalar numbers, this is identity. For matrix elements, this would transpose each element.

Enums

KernelDType

Dtypes supported by dtype-erased kernel entry points.

StridedError

Errors that can occur during strided array operations.

Traits

ComposableElementOp

Trait for element operations that support type-level composition.

Compose

Helper trait for composing two ElementOp types.

ElementOp

Trait for element-wise operations applied to strided views.

ElementOpApply

Trait for types that support element operations (conj, transpose, adjoint).

KernelStorageElement

A scalar type that can safely witness storage for an erased kernel view.

Type Aliases

Result

Result type for strided array operations.
