=head2 (Client) (Server) Dealing with binary data

The choice as JSON as the network transport protocol (because it is the lowest
common denominator across languages like JavaScript, PHP, Python, Ruby, Perl)
makes dealing with binary data requires an extra step or two. The Riap client
libraries are equipped with some features to make this simpler and more
convenient.

First, to make a function that accepts binary data (in its arguments), you need
to specify the argument type as C<buf>. To return binary data as result, you
need to specify C<result>'s schema type as C<buf>. Example:

 package MyLib;
 our %SPEC;
 $SPEC{gzip} = {
     v => 1.1,
     summary => 'Gzip some data',
     args => {
         data => {
             summary => 'Data to compress',
             schema => 'buf*',
             req => 1,
         },
     },
 };
 sub gzip {
     require IO::Compress::Gzip;

     my %args = @_;
     my $compressed;
     IO::Compress::Gzip::gzip($args{data} => $compressed)
         or return [500, "Compression failed"];
     [200, "OK", $compressed];
 }

If you use this function via Riap in-process, there's nothing to worry about
since there is no round-trip to JSON. You can just:

 my $res = Perinci::Access->new->request(call => "/MyLib/gzip",
                                         {args=>{data=>"some data"}});

If you are using this function over HTTP or oher network protocol where JSON is
involved, you will need to encode the argument:

 use MIME::Base64;
 my $res = Perinci::Access->new(riap_version=>1.2)->
               request(call => "http://localhost:5000/api/MyLib/gzip",
                       {args=>{"data:base64"=>encode_base64("some data")}});

Note that you also need to specify Riap version 1.2, as this is the first
version that specifies argument encoding. Also note that the result returned by
the server is actually base64-encoded to be safe to pass through JSON, e.g.:

 [200, "OK", "base64 data...", {"riap.v"=>1.2, "riap.result_encoding"=>"base64"}]

But the Riap client library decodes this automatically for you, so you don't
have to see it.
