Is it possible to declare variables procedurally using Rust macros?

Question

Basically, there are two parts to this question:

1. Can you pass an unknown identifier to a macro in Rust?

2. Can you combine strings to generate

Answer 1

There is also https://github.com/dtolnay/paste, which works well in casese where concat_idents is underpowered or in cases where you can't target the nightly compiler.

macro_rules! foo_macro {
    ( $( $name:ident ),+ ) => {
        paste::item! {
            #[test]
            fn []() {
                assert! false
            }
        }
    };
}
