Transport Layer Security (TLS) where supported (MySQL and PostgreSQL).Īsynchronous notifications using LISTEN and NOTIFY for PostgreSQL. 105 1 6 Hmm, I cannot reproduce your first error ( failed to connect. Supports batch execution and returning results from all statements. Simple (unprepared) query execution including fetching results into the same Row types used by the high-level API. When using the high-level query API (sqlx::query), statements are prepared and cached per connection. Data is read asynchronously from the database and decoded on-demand.Īutomatic statement preparation and caching. Being native Rust, SQLx will compile anywhere Rust is supported.īuilt-in connection pooling with sqlx::Pool. A few steps to show how to use Rust to open a SQLite database and run a query. As the SQLite driver interacts with C, those interactions are unsafe.Ĭross-platform. †† SQLx uses #! unless the SQLite feature is enabled. † The SQLite driver uses the libsqlite3 C library as SQLite is an embedded database (the only way we could be pure Rust for SQLite is by porting all of SQLite to Rust). Works on different runtimes (async-std / tokio / actix) and TLS backends (native-tls, rustls). The Postgres and MySQL/MariaDB drivers are written in pure Rust using zero unsafe†† code. Support for PostgreSQL, MySQL, SQLite, and MSSQL. See SQLx is not an ORM.ĭatabase Agnostic. Built from the ground up using async/await for maximum concurrency.Ĭompile-time checked queries (if you want). SQLx is an async, pure Rust† SQL crate featuring compile-time checked queries without a DSL. We’ll perform CRUD operations using Diesel ORM and SQLx. This article will use a simple classroom database with students to demonstrate each approach. It also enables you to share middleware with applications written using hyper or tonic. In this tutorial, we’ll explore two libraries used when interacting with relational databases in Rust: Diesel and SQLx. This means axum gets timeouts, tracing, compression, authorization, and more, for free. axum doesn't have its own middleware system but instead uses tower::Service. In particular the last point is what sets axum apart from other frameworks. Take full advantage of the tower and tower-http ecosystem of middleware, services, and utilities. 2.19K subscribers 4.5K views 2 years ago I tried going through the diesel tutorial and I ran into an issue that prevented me from using the database they wanted me to use. Generate responses with minimal boilerplate. Simple and predictable error handling model. ![]() Route requests to handlers with a macro-free API.ĭeclaratively parse requests using extractors. If you don't know what Axum is, here is what its page says:Īxum is a web application framework that focuses on ergonomics and modularity. In this article, we will build a little REST API with Axum and Sqlx for the database. In this article, we are going to build a REST API using Axum as a web framework and Sqlx for SQL queries. Let mut conn = Connection::open("cats.I started to use Axum a few weeks ago, honestly, I'm a fan of the framework, so I'm writing this article to document my learning. SeeĬonnection::open will create the database if it doesn't already exist. Historically, the API was based on the one from rust-postgres. Use the rusqlite crate to open SQLite databases. Rusqlite is an ergonomic wrapper for using SQLite from Rust. ![]()
