I put together a little crate to do this based off vbo's answer. It gives you a macro to return or print out the type.

Put this in your Cargo.toml file:

[dependencies]
t_bang = "0.1.2"

Then you can use it like so:

#[macro_use] extern crate t_bang;
use t_bang::*;

fn main() {
  let x = 5;
  let x_type = t!(x);
  println!("{:?}", x_type);  // prints out: "i32"
  pt!(x);                    // prints out: "i32"
  pt!(5);                    // prints out: "i32"
}
