Macro snowboard::response

macro_rules! response {
    ($type:ident) => { ... };
    ($type:ident,$body:expr) => { ... };
    ($type:ident,$body:expr,$headers:expr) => { ... };
    ($type:ident,$body:expr,$headers:expr,$http_version:expr) => { ... };
}

A quick way to create responses.

Usage:

use snowboard::{response, HttpVersion};

// Response with no headers and no body.
let response = response!(bad_request);

// Response with body and no headers.
// Note that $body requires to be convertible to a String.
let response =  response!(internal_server_error, "oopsies");

// Response with body, headers and custom HTTP version.
let body = "everything's fine!";
let headers = vec![("a", "b")];
let response = response!(ok, body, headers, HttpVersion::V1_0);
