Is it expected that everything implement Encodable and Decodable? This was added on Url because someone asked for it, but now that serialize is out of the rustc distribution I’d rather not bother and make it a dev-dependency.

What do you think? Would this be a regression, or does nobody care?

[Ms2ger]

If it was requested for Servo, feel free to get rid of it.

[SimonSapin]

After looking it up: it wasn't for Servo, it was for Iron in #27. @reem, what de you think?

[alexcrichton]

@SimonSapin perhaps an optional dependency?

[reem]

@SimonSapin I requested it because someone wanted iron::Url to implement those traits. Considering they are deprecated I don't mind if those implementations don't go away.

Considering they are deprecated I don't mind if those implementations don't go away.

Did you mean the double negation?

[SimonSapin]

Just taking this as-is was easier than doing the dev-dependency dance. Published v0.2.8.

[reem]

@SimonSapin I didn't. I actually now think that we should be dropping dependencies on rustc-serialize as much as we can, since it's yet another dependency that will need maintenance and updates.

Some rust-url tests still need it to parse a JSON file. I wouldn’t mind switching to another crate that only does JSON, though.
