The FIDL Guides

This is a placeholder for Guides. Our goal here is to provide a language-agnostic (high-level) view of various use cases for FIDL, such as:

• error codes using FIDL enums
• IP addresses using FIDL unions
• fire-and-forget messages (for example, for configuration)
• RPC style messages (when you need to wait for the reply)
• notifications (when you want to receive messages asynchronously)
