sqlx — Async SQL Toolkit for Rust

sqlx is an async-first, pure-Rust SQL toolkit with compile-time query checking. It supports PostgreSQL, MySQL, and SQLite without a DSL — you write raw SQL, and sqlx validates it against a live database at compile time.

Crate Architecture

Module	Purpose
`sqlx::postgres`	PostgreSQL driver (`PgPool`, `PgConnection`, `PgListener`)
`sqlx::mysql`	MySQL driver (`MySqlPool`, `MySqlConnection`)
`sqlx::sqlite`	SQLite driver (`SqlitePool`, `SqliteConnection`)
`sqlx::any`	Database-agnostic driver (`AnyPool`) — no compile-time checking
`sqlx::query_builder`	Runtime dynamic query construction (`QueryBuilder`)
`sqlx::migrate`	Migration framework (`migrate!` macro, `Migrator`)
`sqlx::types`	Type wrappers (`Json<T>`, `Text<T>`)

Quick Start: Minimal Dependency Setup

Always include at least one database driver and a runtime feature. Without a runtime feature, the pool will panic at runtime.
