size required by the format, as reflected by :func:`calcsize`.
-.. function:: unpack_from(format, buffer, offset=0)
+.. function:: unpack_from(format, /, buffer, offset=0)
Unpack from *buffer* starting at position *offset*, according to the format
string *format*. The result is a tuple even if it contains exactly one
platforms, use ``adler32(data) & 0xffffffff``.
-.. function:: compress(data, level=-1)
+.. function:: compress(data, /, level=-1)
Compresses the bytes in *data*, returning a bytes object containing compressed data.
*level* is an integer from ``0`` to ``9`` or ``-1`` controlling the level of compression;
platforms, use ``crc32(data) & 0xffffffff``.
-.. function:: decompress(data, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE)
+.. function:: decompress(data, /, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE)
Decompresses the bytes in *data*, returning a bytes object containing the
uncompressed data. The *wbits* parameter depends on
