RFC: an object-oriented vmod_blob?

[nigoroll]

Asking for feedback: Should we have a different interface to the encode/decode functions provided by vmod_blob? Depending on feedback, I would turn this into a VIP or not.

Quick idea draft:

$Module codec

# decoded form is a blob
$Object blob(ENUM {IDENTITY, BASE64, ...} encoding, ENUM {LOWER, UPPER, DEFAULT} case="DEFAULT"}
$Method STRING encode(BLOB)
$Method BLOB decode(STRANDS)

# decoded form is a string
$Object string(ENUM {IDENTITY, BASE64, ...} encoding, ENUM {LOWER, UPPER, DEFAULT} case="DEFAULT"}
$Method STRING encode(STRING)
$Method STRING decode(STRANDS)

sub vcl_init {
	new myurl = codec.string(URL, LOWER);
}

sub vcl_recv {
	set req.url = "/?url=" + myurl.encode(req.url);
}
