Author here. I've been working on optimizing Python data processing and created
arrayops, a library that accelerates Python's built-in array.array type using Rust.
The Problem:
Python's array.array is memory-efficient but slow. NumPy solves this but is
heavyweight and often overkill for 1D data.
The Solution:
arrayops provides fast operations directly on array.array:
- 10-100x faster than pure Python
- Zero dependencies
- Works with array.array, numpy (1D), memoryview, Arrow
Performance (1M int32 array):
- sum(): 50ms → 0.5ms (100x faster)
- scale(): 80ms → 1.5ms (50x faster)
- All operations use zero-copy buffer access
Key Features:
- Production ready (1.0.0, 100% test coverage)
- MIT licensed
- Full type hints and documentation

Docs: https://arrayops.readthedocs.io
PyPI: https://pypi.org/project/arrayops/
I'd love feedback, especially on:
- Performance optimization approaches
- API design decisions
- Use cases I might have missed
Built with PyO3 (Rust-Python interop) and maturin (packaging).
