SQLx - The Rust SQL Toolkit

SQLx is an async, pure Rust SQL crate featuring compile-time checked queries without a DSL. It is truly Asynchronous. Built from the ground-up using async/await for maximum concurrency. It has support for PostgreSQL, MySQL, SQLite, and MSSQL.

SQLx supports compile-time checked queries. It does not, however, do this by providing a Rust API or DSL (domain-specific language) for building queries. Instead, it provides macros that take regular SQL as an input and ensure that it is valid for your database. The way this works is that SQLx connects to your development DB at compile time to have the database itself verify (and return some info on) your SQL queries.
