$ show SeaQL/sea-orm
SeaORM is a production-grade async ORM for Rust, supporting MySQL, PostgreSQL, and SQLite. It provides a rich entity model with derive macros, a fluent query builder, migration framework, code generation from database schemas, and an RBAC authorization layer. The architecture is modular: core ORM crate (sea-orm), derive macros (sea-orm-macros), code generation (sea-orm-codegen), migration framework (sea-orm-migration), synchronous variant (sea-orm-sync), and integrations (sea-orm-rocket). Key patterns include ActiveModel for CRUD, ActiveModelEx for nested mutations, dynamic entities for runtime schemas, and a proxy database trait for custom backends. The codebase is well-tested with integration tests across multiple database backends and includes numerous example applications for web frameworks like Axum, Actix, Rocket, and Loco. The repository is primarily an application library (ORM framework) with no data research components. It is actively maintained with recent releases and a large community. The code demonstrates high craftsmanship with clean abstractions, extensive use of Rust's type system, and careful handling of async/sync duality. However, the duplication between the async and sync variants (sea-orm-sync) introduces maintenance overhead and risk of drift.
The LLM identified 3 files worth highlighting for reuse:
Defines ProxyDatabaseTrait and ProxyDatabase struct that allow wrapping any DatabaseConnection with custom behavior. This pattern enables transparent proxying of database operations, useful for logging, metrics, or custom backends like Cloudflare D1. The trait is minimal and could be extracted to a separate crate for reuse in other Rust database libraries.
Provides DynamicEntity and DynamicModel for constructing entity definitions at runtime, enabling schema-agnostic queries. This is a non-trivial pattern that bridges static type safety with dynamic database access. The module is self-contained and could be reused in projects needing runtime table/column definitions.
Vendored implementation of topological sort for ordering database tables by foreign key dependencies. Used by the schema registry to determine safe creation order. The algorithm is cleanly implemented with error handling for cycles and could be extracted as a standalone utility for any dependency ordering problem.
