Hands-On Microservices with Rust

Bootstrapping a server

The Rouille framework is very simple to use. It contains start_server functions that expect a function to handle every incoming request. Let's create a main function that uses a diesel crate with an r2d2 pool feature and calls a function to handle requests:

fn main() {     env_logger::init();     let manager = ConnectionManager::<SqliteConnection>::new("test.db");     let pool = Pool::builder().build(manager).expect("Failed to create pool.");     rouille::start_server("127.0.0.1:8001", move |request| {         match handler(&request, &pool) {             Ok(response) => { response },             Err(err) => {                 Response::text(err.to_string())                     .with_status_code(500)             }         }     }) }

We created a ConnectionManager for a local test.db SQLite database and a Pool instance with ...
