Examples

Welcome to the examples! These show off warp's functionality and explain how to use it.

Getting Started

To get started, run examples/hello.rs with:

> cargo run --example hello

This will start a simple "hello world" service running on your localhost port 3030.

Open another terminal and run:

> curl http://localhost:3030/hi
Hello, World!%

Congratulations, you have just run your first warp service!

You can run other examples with cargo run --example [example name]:

• hello.rs - Just a basic "Hello World" API
• routing.rs - Builds up a more complex set of routes and shows how to combine filters
• body.rs - What's a good API without parsing data from the request body?
• headers.rs - Parsing data from the request headers
• rejections.rs - Your APIs are obviously perfect, but for silly others who call them incorrectly you'll want to define errors for them
• futures.rs - Wait, wait! ... Or how to integrate futures into filters
• todos.rs - Putting this all together with a proper app
