If you need someone with Nix installed to test anything, just ping me! |
We are setting the default to `nil`, which means use the default provided by cargo and don't specify it explicitly. If overridden with a string value, that will be used instead and passed as +<toolchain>.

@Icy-Thought could you please test these changes now on Nix? |
|
Sure thing! Will do that when I get home. |

Alright, I just tested the changes and they appear to be working exactly as intended! No errors and the results from Example: #+begin_src rustic :exports both :tangle "shadowing.rs"
fn main() {
let x = 2;
let x = x + 2;
println!("The value of x is {}", x)
}
