iron::itry

macro_rules! itry {
    ($result:expr) => { ... };
    ($result:expr, $modifier:expr) => { ... };
}

Like try!(), but wraps the error value in IronError. To be used in request handlers.

The second (optional) parameter is any modifier. The default modifier is status::InternalServerError.

let f = itry!(fs::File::create("foo.txt"), status::BadRequest);
let f = itry!(fs::File::create("foo.txt"), (status::NotFound, "Not Found"));
let f = itry!(fs::File::create("foo.txt"));  // HTTP 500
