Pull request overview
Adds shape-manipulation operations to mlxcore::Array and updates host extraction (to_vec) to correctly handle non-contiguous views by materializing a row-contiguous buffer first. This expands the safe Rust surface area over MLX-C’s shape/view operators and makes to_vec semantics consistent for transposed/broadcasted arrays.
Changes:
- Update
Array::to_vecto materialize a row-contiguous copy before reading via raw data pointers (fixing transpose/broadcast cases). - Add shape/view ops on
Array:contiguous,reshape,broadcast_to,transpose,squeeze,expand_dims. - Add unit tests covering reshape/transpose/broadcast/squeeze+expand_dims.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Add strides()/is_row_contiguous() computed from public shape+strides, and split to_vec into a fast path (direct bulk read for row-contiguous arrays, the common case) and a slow path (materialize a contiguous copy only for strided/broadcast views). Shared read_buffer helper. Avoids an extra FFI op + CPU-stream copy on every to_vec call. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
