Mojo::ByteStream(3) ByteStream

SYNOPSIS


use Mojo::ByteStream;
# Manipulate bytestream
my $stream = Mojo::ByteStream->new('foo_bar_baz');
say $stream->camelize;
# Chain methods
my $stream = Mojo::ByteStream->new('foo bar baz')->quote;
$stream = $stream->unquote->encode('UTF-8')->b64_encode('');
say "$stream";
# Use the alternative constructor
use Mojo::ByteStream 'b';

DESCRIPTION

Mojo::ByteStream is a scalar-based container for bytestreams that provides a more friendly API for many of the functions in Mojo::Util. 

  # Access scalar directly to manipulate bytestream
  my $stream = Mojo::ByteStream->new('foo');
  $$stream .= 'bar';
