rust - How to "use another-file" in rust? Module with hyphens in it

Question

Using another_file with underscore in as word separators works fine in Rust.

How do i use hyphens instead (another-file.rs)?

// another-file.rs
pub fn method() { }

// lib.rs
use another_file;        // <-- ERROR can not find another_file.rs
another_file::method();

您必须显式声明模块并提供其路径：

#[path="../path/to/another-file.rs"]
mod another_file;

use another_file;

然而，这并不常见，我不会推荐它。只需坚持使用 snake_case 作为模块名称即可。
