NAME

IO::Uncompress::Brotli - Read Brotli buffers/streams

SYNOPSIS

use IO::Uncompress::Brotli;

# uncompress a buffer
my $decoded = unbro $encoded;

# uncompress a stream
my $bro = IO::Uncompress::Brotli->create;
while(have_input()) {
   my $block = get_input_block();
   my $decoded_block = $bro->decompress($block);
   handle_output_block($decoded_block);
}

DESCRIPTION

IO::Uncompress::Brotli is a module that decompresses Brotli buffers and streams. Despite its name, it is not a subclass of IO::Uncompress::Base and does not implement its interface. This will be rectified in a future release.

One-shot interface

If you have the whole buffer in a Perl scalar use the unbro function.

unbro($input)

Takes a whole compressed buffer as input and returns the decompressed data. This function relies on the BrotliDecompressedSize function. In other words, it only works if the buffer has a single meta block or two meta-blocks where the first is uncompressed and the second is empty.

Exported by default.

Streaming interface

If you want to process the data in blocks use the object oriented interface. The available methods are:

IO::Uncompress::Brotli->create

Returns a IO::Uncompress::Brotli instance. Please note that a single instance cannot be used to decompress multiple streams.

$bro->decompress($block)

Takes the a block of compressed data and returns a block of uncompressed data. Dies on error.
