IO::Uncompress::Brotli(3)

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

SYNOPSIS
  use IO::Uncompress::Brotli;

  # uncompress a buffer (yielding at most 10MB)
  my $decoded = unbro $encoded, 10_000_000;

  # 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, $maximum_decoded_size)
    Takes a whole compressed buffer as input and returns the decompressed data. It allocates a buffer of size $maximum_decoded_size to store the decompressed data, if this is not sufficient (or there is another error) this function will croak.

    As of version 0.004_002, the $maximum_decoded_size argument is optional. If not provided, unbro uses the streaming interface described in the next section to decompress the buffer in blocks of one megabyte. The decompressed blocks are concatenated and returned.

    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.
