Rust for C-Programmers

9.13 Visibility and Modules

By default, structs and their fields are private within the module. Use pub to expose them:

pub struct PublicStruct {
    pub field: Type,
    private_field: Type,
}

You will learn more about modules, crates, and structuring larger projects later. Remember that visibility in Rust is explicit—fields and structs are private unless declared pub.
