Static rustc_lint::builtin::SPECIAL_MODULE_NAME

pub static SPECIAL_MODULE_NAME: &Lint

The special_module_name lint detects module declarations for files that have a special meaning.

Example

mod lib;

fn main() {
    lib::run();
}

{{produces}}

Explanation

Cargo recognizes lib.rs and main.rs as the root of a library or binary crate, so declaring them as modules will lead to miscompilation of the crate unless configured explicitly.

To access a library from a binary target within the same crate, use your_crate_name:: as the path instead of lib:::

// bar/src/lib.rs
fn run() {
    // ...
}

// bar/src/main.rs
fn main() {
    bar::run();
}

Binary targets cannot be used as libraries and so declaring one as a module is not allowed.
