Directory structure

As explained in Rust Servers, Services, and Apps

A project structure is the organization of a software project's files, directories, modules, and related artifacts.

As a Rust web service grows, organize database access, handlers, and models into folders instead of letting each area remain a single file. This shortens individual files and makes code quicker to find, at the cost of added structural complexity. section 6.1

One layout for the evolving service keeps application concerns distinct:

• `src/bin/iter5.rs` contains `main()`; `src/iter5/routes.rs` holds routes, and `state.rs` and `errors.rs` hold application state and error handling. section 6.1
• Group course and tutor database access under `dbaccess`, and organize handlers and models into their own folders. section 6.1
• Keep supporting artifacts in view too: database scripts live under `src/iter5/dbscripts`, while `.env` holds database credentials and should not be checked into the repository. section 6.1

How Rust Servers, Services, and Apps covers it

How deep it goes

Shows a concrete file-and-folder reorganization and its tradeoff, without detailing every resulting file.

Examples

Uses a course-and-tutor service layout with separate database-access, handler, and model folders.

What it assumes

Assumes familiarity with Actix Web services, relational database CRUD, and error handling.

What you can do after

Apply Rust modules to reorganize a growing service into navigable, responsibility-focused folders.

How it connects

Connects project structure to Rust modules, Actix Web, database access, handlers, models, and code refactoring.
