17.5 Summary
Rust’s layered architecture—packages, crates, and modules—provides a well-defined system for code organization. Here’s a concise review:
- Packages: High-level sets of one or more crates, managed by Cargo.
- Crates: Individual compilation units, compiled independently into libraries or executables.
- Modules: Namespaced subdivisions of a crate, controlling internal organization and visibility.
Though these concepts may initially seem more elaborate than a traditional C workflow, they excel at preventing name collisions, clarifying boundaries, and helping large teams maintain and extend a shared codebase.
