+# Running Asynchronous Code
+An HTTP server should be able to serve multiple clients concurrently;
+that is, it should not wait for previous requests to complete before handling the current request.
+The book
+[solves this problem](https://doc.rust-lang.org/book/ch20-02-multithreaded.html#turning-our-single-threaded-server-into-a-multithreaded-server)
+by creating a thread pool where each connection is handled on its own thread.
+Here, instead of improving throughput by adding threads, we'll achieve the same effect using asynchronous code.
+-->
+
+# Exécuter du code asynchrone
+
+Un serveur HTTP doit être capable de servir plusieurs clients en concurrence,
+et par conséquent, il ne doit pas attendre que les requêtes précédentes soient
+terminées pour s'occuper de la requête en cours.
+Le livre Rust [résout ce
+problème](https://jimskapt.github.io/rust-book-fr/ch20-02-multithreaded.html#transformer-notre-serveur-monot%C3%A2che-en-serveur-multit%C3%A2ches)
+en créant un groupe de tâches où chaque connexion est gérée sur son propre
+processus. Nous allons obtenir le même effet en utilisant du code asynchrone,
+au lieu d'améliorer le débit en ajoutant des processus.
+
+<!--
+Let's modify `handle_connection` to return a future by declaring it an `async fn`:
+```rust,ignore
+{{#include ../../examples-sources/09_02_async_tcp_server/src/main.rs:handle_connection_async}}
+```
+-->
+
+Modifions le `gestion_connexion` pour retourner une future en la déclarant
+comme étant une fonction asynchrone :
+
+```rust,ignore
+{{#include ../../examples/09_02_async_tcp_server/src/main.rs:handle_connection_async}}
+```
+
+<!--
+Adding `async` to the function declaration changes its return type
+from the unit type `()` to a type that implements `Future<Output=()>`.
+-->
+
+L'ajout de `async` à la déclaration de la fonction change son type de retour de
+`()` à un type qui implémente `Future<Output=()>`.
+
+<!--
+If we try to compile this, the compiler warns us that it will not work:
+```console
+$ cargo check
+    Checking async-rust v0.1.0 (file:///projects/async-rust)
+warning: unused implementer of `std::future::Future` that must be used

+   |
+   = note: `#[warn(unused_must_use)]` on by default
+   = note: futures do nothing unless you `.await` or poll them
+```
+-->
+
+Si nous essayons de compiler cela, le compilateur va nous avertir que cela ne
+fonctionnera pas :
+
+```console
+$ cargo check
+    Checking async-rust v0.1.0 (file:///projects/async-rust)

+   |
+   = note: `#[warn(unused_must_use)]` on by default
+   = note: futures do nothing unless you `.await` or poll them
+```
+
+<!--
+Because we haven't `await`ed or `poll`ed the result of `handle_connection`,
+it'll never run. If you run the server and visit `127.0.0.1:7878` in a browser,
+you'll see that the connection is refused; our server is not handling requests.
+-->
+
+Comme nous n'avons pas utilisé `await` ou `poll` sur le résultat de
+`gestion_connexion`, cela ne va jamais s'exécuter. Si vous lancez le serveur et
+visitez `127.0.0.1:7878` dans un navigateur web, vous constaterez que la
+connexion est refusée, notre serveur ne prend pas en charge les requêtes.
+
+<!--
+We can't `await` or `poll` futures within synchronous code by itself.
+We'll need an asynchronous runtime to handle scheduling and running futures to completion.
+Please consult the [section on choosing a runtime](../08_ecosystem/00_chapter.md)
+for more information on asynchronous runtimes, executors, and reactors.
+Any of the runtimes listed will work for this project, but for these examples,
+we've chosen to use the `async-std` crate.
+-->
+
+Nous ne pouvons pas utiliser `await` ou `poll` sur des futures dans du code
+synchrone tout seul.
+Nous allons avoir besoin d'un environnement d'exécution asynchrone pour gérer
+la planification et l'exécution des futures jusqu'à ce qu'elles se terminent.
+Vous pouvez consulter la [section pour choisir un environnement
+d'exécution](../08_ecosystem/00_chapter.md) pour plus d'information sur les
+environnements d'exécution, exécuteurs et réacteurs asynchrones.
+Tous les environnements d'exécution listés vont fonctionner pour ce projet,
+mais pour ces exemples, nous avons choisi d'utiliser la crate `async-std`.
+
+<!--
+## Adding an Async Runtime
+The following example will demonstrate refactoring synchronous code to use an async runtime; here, `async-std`.
+The `#[async_std::main]` attribute from `async-std` allows us to write an asynchronous main function.
+To use it, enable the `attributes` feature of `async-std` in `Cargo.toml`:
+```toml
+[dependencies.async-std]
+version = "1.6"
+features = ["attributes"]
+```
+-->
+
+## Ajouter un environnement d'exécution asynchrone
+
+L'exemple suivant va monter le remaniement du code synchrone pour utiliser un
+environnement d'exécution asynchrone, dans ce cas `async-std`.
+L'attribut `#[async_std::main]` de `async-std` nous permet d'écrire une
+fonction `main` asynchrone.
+Pour l'utiliser, il faut activer la fonctionnalité `attributes` de `async-std`
+dans `Cargo.toml` :
+
+```toml
+[dependencies.async-std]
+version = "1.6"
+features = ["attributes"]
+```
+
+<!--
+As a first step, we'll switch to an asynchronous main function,
+and `await` the future returned by the async version of `handle_connection`.
+Then, we'll test how the server responds.
+Here's what that would look like:
+```rust
+{{#include ../../examples-sources/09_02_async_tcp_server/src/main.rs:main_func}}
+```
+Now, let's test to see if our server can handle connections concurrently.
+Simply making `handle_connection` asynchronous doesn't mean that the server
+can handle multiple connections at the same time, and we'll soon see why.
+-->
+
+Pour commencer, nous allons changer pour une fonction `main` asynchrone, et
+utiliser `await` sur la future retournée par la version asynchrone de
+`gestion_connexion`. Ensuite, nous testerons comment le serveur répond. Voici à
+quoi cela ressemblerait :
+
+```rust
+{{#include ../../examples/09_02_async_tcp_server/src/main.rs:main_func}}
+```
+
+Maintenant, testons pour voir si notre serveur peut gérer les connexions en
+concurrence. Transformer simplement `gestion_connexion` en asynchrone ne
+signifie pas que le serveur puisse gérer plusieurs connexions en même temps, et
+nous allons bientôt voir pourquoi.
+
+<!--
+To illustrate this, let's simulate a slow request.
+When a client makes a request to `127.0.0.1:7878/sleep`,
+our server will sleep for 5 seconds:
+-->
+
+Pour illustrer cela, simulons une réponse lente.
+Lorsqu'un client fait une requête vers `127.0.0.1:7878/pause`, notre serveur va
+attendre 5 secondes :
+
+<!--
+```rust,ignore
+{{#include ../../examples-sources/09_03_slow_request/src/main.rs:handle_connection}}
+```
+This is very similar to the 
+[simulation of a slow request](https://doc.rust-lang.org/book/ch20-02-multithreaded.html#simulating-a-slow-request-in-the-current-server-implementation)
+from the Book, but with one important difference:
+we're using the non-blocking function `async_std::task::sleep` instead of the blocking function `std::thread::sleep`.
+It's important to remember that even if a piece of code is run within an `async fn` and `await`ed, it may still block.
+To test whether our server handles connections concurrently, we'll need to ensure that `handle_connection` is non-blocking.
+-->
+
+```rust,ignore
+{{#include ../../examples/09_03_slow_request/src/main.rs:handle_connection}}
+```
+
+C'est très ressemblant à la [simulation d'une requête
+lente](https://jimskapt.github.io/rust-book-fr/ch20-02-multithreaded.html#simuler-une-longue-requ%C3%AAte-%C3%A0-traiter-avec-limpl%C3%A9mentation-actuelle-du-serveur)
+dans le livre Rust, mais avec une différence importante :
+nous utilisons la fonction non bloquante `async_std::task::sleep` au lieu de la
+fonction bloquante `std::thread::sleep`.
+Il est important de se rappeler que même si un code est exécuté dans une
+fonction asynchrone et qu'on utilise `await` sur elle, elle peut toujours
+bloquer.
+Pour tester si notre serveur puisse gérer les connexions en concurrence, nous
+avons besoin de nous assurer que `gestion_connexion` n'est pas bloquante.
+
+<!--
+If you run the server, you'll see that a request to `127.0.0.1:7878/sleep`
+will block any other incoming requests for 5 seconds!
+This is because there are no other concurrent tasks that can make progress
+while we are `await`ing the result of `handle_connection`.
+In the next section, we'll see how to use async code to handle connections concurrently.
+-->
+
+Si vous exécutez le serveur, vous constaterez qu'une requête vers
+`127.0.0.1:7878/pause` devrait bloquer toutes les autres requêtes entrantes
+pendant 5 secondes !
+C'est parce qu'il n'y a pas d'autres tâches concurrentes qui peuvent progresser
+pendant que nous utilisons `await` sur le résultat de `gestion_connexion`.
+Dans la prochaine section, nous allons voir comment utiliser du code asynchrone
+pour gérer en concurrence les connexions.
