Macro mod_from

macro_rules! mod_from {
    ($vis:vis $module_name:ident) => { ... };
    ($vis:vis $module_name:ident, $module_path_str:literal) => { ... };
}

Declares a module by including a Rust source file relative to the project’s directory.

The macro generates a mod declaration and inserts the contents of the specified file into the module. This is a more ergonomic alternative to manually wrapping include! within a module declaration.

Usage

• To declare a module using its name:

// Declares `pub(super) mod helper` with contents from "helper.rs":
mod_from!(pub(super) helper);

• To declare a module with a specific path:

// Declares `mod helper` with contents from "src/helper.rs":
mod_from!(helper, "src/helper.rs");
