SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies database interactions in Rust by providing compile-time checked SQL queries, reducing runtime errors and improving developer confidence.

Core Features & Use Cases

Compile-Time Safety: Ensures SQL queries are valid against your database schema before runtime.
Async Support: Seamless integration with asynchronous Rust applications.
Type Safety: Maps query results directly to Rust structs, preventing type mismatches.
Use Case: Develop a robust backend service in Rust that interacts with a PostgreSQL database, ensuring all database operations are validated during compilation.

Quick Start

Use the SQLx Database skill to connect to a PostgreSQL database using the provided connection string.

FAQPage Schema

How do I validate Rust SQL queries against a PostgreSQL schema at compile time?▼

Compile-time checked SQL queries validate Rust SQL queries against a PostgreSQL schema during compilation using the sqlx library, catching syntax and type errors before runtime to reduce application failures.

How do I map PostgreSQL query results to Rust structs asynchronously?▼

Mapping PostgreSQL query results to Rust structs is handled by sqlx through asynchronous database connections, directly type-checking and mapping query outputs to Rust structs to prevent runtime type mismatches.

Can I manage database connection pooling and transactions in async Rust?▼

Yes, managing database connection pooling and transactions in async Rust is supported by sqlx, facilitating connection pooling and transaction management for PostgreSQL and other supported databases.

What is the best way to handle schema evolution in a Rust backend?▼

Handling schema evolution in a Rust backend is best achieved by integrating sqlx migration tools, which manage database schema evolution alongside compile-time validated SQL queries.

Why use compile-time checked queries instead of runtime SQL validation in Rust?▼

Using compile-time checked queries instead of runtime SQL validation in Rust ensures SQL queries are valid against your database schema before runtime, reducing runtime errors and improving developer confidence.
