@ribrea There's no hyper::header::ContentType. Why do you think there should be?

[arianxplore]

Same reason Status code is exist,

I was writing a macro to response as JSON,
i thought is better to use "application/json" as a constant.

[olix0r]

There's a separate mime crate that includes types for handling content-type, etc. I assume the context for keeping them separate is to avoid these types being a part of Hyper's stable API.
