Mist's module system was created to fix Rust's dreaded parent-declared module system, files declare themselves and their publicity via `pub module my_mod;` as the first statement.
```mist ```mist
// Declare a submodule // Declare a module
pub module foo; pub module foo;
// Import // Import
use std::collections::HashMap; use std::collections::HashMap;
// Re-exporting import // Re-exporting import (alias)
pub use my_module::MyType; pub use my_module::MyType;
``` ```

A `package.mist` file acts as a directory's module root, analogous to `mod.rs`. A `package.mist` file acts as a directory's module root, analogous to `mod.rs`, but it's not required, as long as the directory contains `.mist` files, it will auto generate `mod.rs`.
#### *💡 Tip*: File names don't matter, `module my_mod` determines the name.
