Correct use/import syntax

help

Hey all, n00b here.

I'm having trouble importing a script correctly, so I can begin building the script, but if the compiler can't find the script I want to build, I'm stuck. I'm reading the rust book trying to figure this out and I'm not having any luck so far.

The error

Preciate you!

You need to declare the layers and layers::menu_layer modules, starting in your src/main.rs file. Same as you did with the gui_zpu module. Otherwise the src/layers/menu_layer.rs file won't be compiled as part of your binary.

This means changing your src/main.rs file:

use cursive::Cursive;
use cursive::CursiveExt; // Import CursiveExt for run method
mod gui_zpu;
+ pub mod layers;

fn main() {
    let mut siv = Cursive::default();
    gui_zpu::initialize(&mut siv); // Initialize GUI from gui_zpu

    siv.run();
}

and adding a file src/layers.rs or src/layers/mod.rs that declares the menu_layer submodule:

pub mod menu_layer;
