AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

fastar wraps Rust tar, flate2, and zstd crates to provide high-performance creation and extraction of compressed and uncompressed tar archives in Python.

Medium install friction due to compiled wheels; however, the package is actively maintained with recent releases and provides pre-built wheels across Python 3.8–3.14 and multiple platforms (Linux, macOS, Windows, ARM), reducing build-time overhead for most users.

Licensed under MIT (permissive), allowing free use, modification, and distribution with minimal restrictions—suitable for both open-source and commercial projects.

Usage

pip install fastar

import fastar
from pathlib import Path

with fastar.open("archive.tar", "w") as archive:
    archive.append(Path("file.txt"))

with fastar.open("archive.tar", "r") as archive:
    archive.unpack("output/")

Requires Python 3.8 or later; compiled wheels available for most platforms, but build from source may require Rust toolchain.

Verdict: fastar is an actively maintained, zero-dependency Rust-backed archive library with broad platform coverage and permissive licensing. No known vulnerabilities and strong Python version support (3.8–3.14) make it a solid choice for high-performance tar operations, though medium install friction from compilation is typical for native-extension packages.
