Rocket launch and hyperspin tutorial2/9/2022 Routes are declared by annotating a function, the handler, with the set of parameters to match against. Rocket uses attributes, which look like function decorators in other languages, to make declaring routes easy. The parameters to match against include static paths, dynamic paths, path segments, forms, query strings, request format specifiers, and body data. A handler to process the request and return a response.Ī handler is simply a function that takes an arbitrary number of arguments and returns any arbitrary type.A set of parameters to match an incoming request against.Rocket applications are centered around routes and handlers. The sections following describe the request and response phases as well as other components of Rocket. The remainder of this section details the routing phase as well as additional components needed for Rocket to begin dispatching requests to request handlers. ![]() ![]() Rocket continues listening for requests, restarting the lifecycle for each incoming request. Rocket generates the appropriate HTTP response and sends it to the client. Processing completes by returning a Response. This is the main business logic of an application. The request handler associated with the route is invoked with validated arguments. If validation fails, Rocket forwards the request to the next matching route or calls an error handler. Rocket validates the incoming request against types and guards present in the matched route. Rocket determines which request handler to invoke by matching against route attributes declared in your application. ROCKET LAUNCH AND HYPERSPIN TUTORIAL CODERocket parses an incoming HTTP request into native structures that your code operates on indirectly. We summarize the lifecycle as the following sequence of steps: We call the process that goes from request to response the "lifecycle". Rocket's main task is to listen for incoming web requests, dispatch the request to the application code, and return a response to the client. Your application code instructs Rocket on what to pre-process and post-process and fills the gaps between pre-processing and post-processing. Rocket provides primitives to build web servers and applications with Rust: Rocket provides routing, pre-processing of requests, and post-processing of responses the rest is up to you.
