Cornucopia is a Rust code generator that produces type-checked Rust interfaces from PostgreSQL queries. It validates queries against a live database and emits a standalone crate with type-safe, high-performance database access functions.

Use cases

• generate type-safe Rust code from PostgreSQL queries
• catch SQL errors at compile time instead of runtime
• write SQL-first database access without an ORM
• map custom Postgres types and enums to Rust structs
• generate sync and async database clients with connection pooling

When to choose

• you prefer writing plain SQL over ORM query builders
• you want compile-time guarantees that queries match your schema
• you need performance close to hand-written rust-postgres code
• you use PostgreSQL-specific features like custom types, enums, and arrays

When to avoid

• you need multi-database support beyond PostgreSQL
• you want a runtime ORM or dynamic query builder
• your project does not use Rust
