And your **FastAPI** application might also be composed of several files/modules, etc.

### **FastAPI** app file { #fastapi-app-file }

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

In the file `main.py` you have your **FastAPI** app:

        }

        return bufferIndex - start;
    }

    @Override
    public int size() {
        return 20; // Fixed size: 2 + 2 + 4 + 12 (transform structure)
    }

    /**
     * Check if RDMA is supported based on this context
     *
     * @return true if RDMA Transform V1 is supported
     */
    public boolean isRdmaSupported() {

 * The local repository serves as a cache for downloaded remote artifacts and storage
 * for locally installed artifacts. This manager provides services to determine the
 * appropriate paths for artifacts within the local repository structure.
 *
 * <p>The LocalRepositoryManager is responsible for:
 * <ul>
 *   <li>Determining the storage path for locally installed artifacts</li>
 *   <li>Managing the layout and organization of cached remote artifacts</li>

# Tutoriel - Guide utilisateur - Introduction

Ce tutoriel vous montre comment utiliser **FastAPI** avec la plupart de ses fonctionnalités, étape par étape.

Chaque section s'appuie progressivement sur les précédentes, mais elle est structurée de manière à séparer les sujets, afin que vous puissiez aller directement à l'un d'entre eux pour résoudre vos besoins spécifiques en matière d'API.
