Pull request overview

This pull request contains multiple week submissions (Week 2, 3, 4, and 5) for a Rust learning curriculum. The primary focus is Week 5 Day 1, which introduces a Rust Scaffold CLI tool that generates opinionated project structures for Axum and Actix-web frameworks.

Changes:

Week 5 Day 1: New Rust Scaffold CLI project with template-based project generation for web frameworks
Week 4 Day 1: Blog API project using Axum with CRUD operations for blog posts
Week 3 Day 3: CLI grep-like tool for searching text in files
Week 2 submissions: Expense tracker and user input handling exercises

There is significant code duplication between the framework.rs file and the template files. The dependencies method in framework.rs (lines 28-81) contains the exact same content as the DEPENDENCIES constants in templates/axum.rs and templates/actix.rs. Similarly, main_rs_content (lines 84-161), router_mod_content (lines 164-204) duplicate content from the template modules. This violates the DRY (Don't Repeat Yourself) principle and makes maintenance harder. Consider removing the duplicated code from framework.rs and instead using the constants from the templates module directly.

+#[derive(Debug,Clone)]
+
+// pub struct AppState {
+//     pub db_pool: PgPool,

+
+impl Default for AppState {
+    fn default() -> Self {
+        Self::new()

+}


The app_state module is not declared in main.rs, so this file is not part of the compilation unit. The code in this file references types (RwLock, HashMap, Author, BlogPost) and a function (seed_authors) that are either not imported or not accessible. This will prevent the project from compiling. To fix this, either integrate this code into models.rs or add "mod app_state;" to main.rs and ensure all necessary imports are present.

Missing space after comma in function parameters. The formatting should be "state: &AppState, payload: CreatePostRequest" for better readability and consistency with Rust style guidelines.

state: &AppState,

+            Uuid::new_v4(),

+        ),
+    ];
+
+    authors.into_iter().map(|a| (a.id, a)).collect()
+}


The AppState struct is not defined in this file, but it is imported from models in other files (e.g., handlers.rs, services.rs). The actual AppState definition exists in app_state.rs but that module is not connected to the main.rs module tree. Additionally, the seed_authors function defined on line 77 is used by AppState::new() in app_state.rs but is not accessible because it's in a different module. This will cause compilation errors. Consider either: 1) Moving AppState and seed_authors to this file and making seed_authors public, or 2) Adding app_state as a module in main.rs and adjusting imports accordingly.
