pymft-rs

Python bindings for https://github.com/omerbenamram/mft/.

Installation

Available on PyPi - https://pypi.org/project/mft/.

To install from PyPi - pip install mft

Wheels

Wheels are built using the abi3 tag, so a single wheel works for CPython 3.10 and newer. Free-threaded CPython 3.14 (python3.14t) gets its own cp314t wheel; importing mft there keeps the GIL disabled, and parsers can be created on one thread and consumed on another.

Supported platforms are:

• Linux x86_64 and aarch64 (manylinux and musllinux; aarch64 and musl are cross-compiled with zig)
• macOS universal2 (x86_64 + arm64)
• Windows x86_64

The package ships type stubs (mft.pyi), checked against the compiled module in CI with mypy.stubtest.

Installation from sources

Installation is possible for other platforms by installing from sources.

This requires a Rust compiler and a recent enough Pip.

Run pip install -e .

Usage

Note that the iterators created by parser.entries() and entry.attributes() may return RuntimeError objects if there was an error while trying to parse one of the attributes, so check them before continuing.

from mft import PyMftParser, PyMftAttributeX10, PyMftAttributeX30

def main():
    parser = PyMftParser("/Users/omerba/Workspace/pymft-rs/samples/MFT")
    for entry_or_error in parser.entries():
        if isinstance(entry_or_error, RuntimeError):
            continue

        print(f'Entry ID: {entry_or_error.entry_id}')

        for attribute_or_error in entry_or_error.attributes():
            if isinstance(attribute_or_error, RuntimeError):
                continue

            resident_content = attribute_or_error.attribute_content
            if resident_content:
                if isinstance(resident_content, PyMftAttributeX10):
                    print(f'Found an X10 attribute')
                    print(f'Modified: {resident_content.modified}')
                if isinstance(resident_content, PyMftAttributeX30):
                    print(f'Found an X30 attribute')
                    print(f'Modified: {resident_content.modified}')
                    print(f'Name: {resident_content.name}')

        print('--------------------------------')
