NAME

6       Compress::Stream::Zstd - Perl interface to the Zstd (Zstandard)
7       (de)compressor
8

NOTE

10       This module is a fork of Compress-Zstd
11       <https://github.com/spiritloose/Compress-Zstd>.  It contains a few
12       changes to make streaming compression/uncompression more robust.  The
13       only reason for this fork is to allow the module to work with
14       `IO-Compress-Zstd`.  The hope is that the changes made here can be
15       merged back upstream and this module can be retired.
16

SYNOPSIS

18           use Compress::Stream::Zstd;
19
20           my $compressed = compress($bytes);
21           my $decompressed = decompress($compressed);
22
