Autocompletion issues with Iron's Hello World.

[crinklywrappr]

Racer fails to provide autocompletion for the following code in the listed parts.

• Ok(Response::
• Ok(Response::with((status::
• let _server = Iro (doesn't respond with 'Iron')
• let _server = Iron::
• let _server = Iron::new(hello_world).
• let _server = Iron::new(hello_world).http("localhost:3000").

This is the "Hello World" program on the frontpage of the Iron website here.

extern crate iron;

use iron::prelude::*;
use iron::status;

fn main() {
    fn hello_world(_: &mut Request) -> IronResult<Response> {
        Ok(Response::with((status::Ok, "Hello World!")))
    }

    let _server = Iron::new(hello_world).http("localhost:3000").unwrap();
    println!("On 3000");
}

Code compiles and runs using Rust 1.12.1 and Iron 1.4.0

Just tried with 20161017.1829. Same problem.

Please update to the latest version of racer.el, and run M-x racer-debug. Paste the result here :)

I get this:

The last racer command was:

$ cd /home/mattiasb/test/racer-test/
$ export CARGO_HOME=/home/mattiasb/.cargo
$ export RUST_SRC_PATH=/home/mattiasb/Code/rust-lang/rust/src/

$ /home/mattiasb/.local/bin/racer complete 8 21 /home/mattiasb/test/racer-test/test.rs /tmp/racer174475oZ

This command terminated with exit code 0.

stdout:

PREFIX 21,21,
END

No output on stderr.

The temporary file will have been deleted. You should be able to reproduce
the same output from racer with the following command:

$ CARGO_HOME=/home/mattiasb/.cargo RUST_SRC_PATH=/home/mattiasb/Code/rust-lang/rust/src/ /home/mattiasb/.local/bin/racer complete 8 21 /home/mattiasb/test/racer-test/test.rs

Please report bugs on GitHub.

And this is with the above code with the pointer right after "Response::"

Thanks.

I'm afraid this looks like an issue with racer rather than racer.el -- would you mind filing a bug upstream?

[crinklywrappr]

Done

[Wilfred]

Not a racer.el issue as far as I can see, closing in favour of upstream bug.
