The pyzstd module provides Python support for Zstandard, using
an API style similar to the bz2, lzma, and zlib modules.
[!WARNING]
Zstandard is now natively supported in Python’s standard library via the
compression.zstdmodule. For older Python versions, use thebackports.zstdlibrary as a fallback.We recommend new projects to use the standard library, and existing ones to consider migrating.
pyzstdinternally usescompression.zstdsince version 0.19.0.See
pyzstd's documentation for details and a migration guide.
