Mojo::ByteStream - ByteStream


  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 qw(b);
  my $stream = b('foobarbaz')->b64_encode('')->say;


L<Mojo::ByteStream> is a scalar-based container for bytestreams that provides a more friendly API for many of the
