How to access const values from bin to lib

[Joe232]

Hey guys so if I have a bin and it connects to a lib, and in the main.rs file I have a const

pub const DEBUG: bool       = true;

Inside one of the lib project files, how would I exactly access this variable?

Your binary can access code from your library, but your library cannot access code from your binary.

Any code shared across both crates should be in the library.

does the const DEBUG need to be inside the binary?

you can define it as a static inside your library and then set it inside the binary

lib:

static DEBUG: Lazy<Mutex<bool>> = Lazy::new(Mutex::default);

fn set_debug(b: bool) { .. }

bin:

fn main() {
    set_debug(true)
}
