pyzsync
A Python module written in Rust that implements the zsync algorithm.
Usage
Use the Python module as a script
# Show help.
uvx --with pyzsync python -m pyzsync --help
# Create a zsync file.
uvx --with pyzsync python -m pyzsync zsyncmake bigfile
# Compare two files and show how much data from the first file
# can be used to create the second file using the zsync algorithm.
uvx --with pyzsync python -m pyzsync compare bigfile1 bigfile2
# Download a file using zsync.
# This will automatically use blocks from the local files
# noble-desktop-amd64.iso and noble-desktop-amd64.iso.zsync-tmp-*
# if available.
uvx --with pyzsync python -m pyzsync zsync https://cdimage.ubuntu.com/daily-live/current/noble-desktop-amd64.iso.zsync
Use the Python module in a script
from pyzsync import create_zsync_file
create_zsync_file("bigfile", "bigfile.zsync")
See tests/test_pyzsync.py and pyzsync/__main__.py for more examples.
