cot ★ 1082 58 APPLICATION

Cot is a batteries-included web framework for Rust, heavily inspired by Django. It provides a full-stack application architecture with an ORM (SQLite, PostgreSQL, MySQL), automatic migration generation, an admin panel, form handling with validation, session management (multiple backends including file, database, Redis), caching (in-memory, Redis), email sending (console, SMTP), OpenAPI/Swagger documentation generation, static file serving, and a CLI for project scaffolding and migration management. The framework is built on top of tokio, axum, sea-query, sqlx, and tower, using trait-based designs and an extensive set of procedural macros (e.g., `#[model]`, `#[Form]`, `#[AdminModel]`, `#[IntoResponse]`, `query!`, `#[cot::main]`) to reduce boilerplate. Architecturally, Cot uses a type-safe phased bootstrapper (the `Bootstrapper` with six states from `Uninitialized` to `Initialized`) to configure the project in a guaranteed order. The central `Project` and `App` traits define the application composition, while the `Router` (trie-based) supports nested routing and reverse URL generation. The ORM layer features a query expression builder, migration engine with dependency-aware rollback, and backend-specific implementations. The macro system (`cot-macros` + `cot-codegen`) performs compile-time code generation for models, forms, queries, and admin interfaces, with UI compile-fail tests to validate error messages. The codebase demonstrates high craftsmanship with well-separated concerns, extensive test coverage (unit, integration, snapshot, UI compile-fail, and end-to-end WebDriver tests), and reusable patterns such as composable response modifiers, builder-pattern configuration, and a custom serde deserializer for path parameters. While the framework is relatively new and some features like workspace migration generation are incomplete, it is actively maintained with frequent releases and a healthy CI/CD pipeline.
