Serwus is a set of helpers for building actix-web/diesel based services.

Features

• MultiPool - Master/replica-aware wrapper for r2d2
• StatsPresenter - Framework for readiness and statistics reporting
• JsonError - Middleware that makes actix-web return errors as JSONs

Example

use serwus::{
    server::{Serwus, default_cors},
    EmptyStats,
    web,
};

#[derive(Clone, EmptyStats)]
pub struct AppData;

async fn hello() -> &'static str {
    "Hello world\n"
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    let prepare_app_data = || AppData;

    Serwus::default()
        .start(
            prepare_app_data,
            |app| {
                app.route("/", web::get().to(hello));
            },
            default_cors,
