Hands-On Microservices with Rust

Tasks handler

tasks_handler locks a Mutex with IndexMap to iterate over all Record values to render them as a part of the Tasks struct:

fn tasks_handler(req: HttpRequest<State>) -> impl Future<Item = HttpResponse, Error = WebError> {    let tasks: Vec<_> = req        .state()        .tasks        .lock()        .unwrap()        .values()        .cloned()        .collect();    let tmpl = Tasks { tasks };    future::ok(HttpResponse::Ok().body(tmpl.render().unwrap()))}

If you remember, we added the askama crate to render templates. Create a templates folder in the root of project and add a tasks.html file with some HTML code that contains at least the following rendering table:

<table>    <thead>        <tr>            <th>Task ID</th>            <th>Timestamp</th>            <th>Status</th>        </tr>    </thead>    <tbody>        {% for task in tasks %} <tr> ...
