This crate exposes the ct-for!() macro, which can be used to repeat code n times with a substitution.
For example:
rust
let c = 17;
ct_for!(x in ["5", 6, c, vec![5, 6, 7]]
println!("{:?}", x);
);
expands to:
rust
let c = 17;
println!("{:?}", "5");
println!("{:?}", 6);
println!("{:?}", c);
println!("{:?}", vec![5, 6, 7]);
The ct_for!() macro can also be nested.
There really isn't much more to it.
