Rust Http Server

This is a basic example of a server built with Rust using the Warp web framework. This server has a single route (/) that responds with a JSON message.

Features

• Uses the Warp framework for handling HTTP requests.
• Provides an endpoint (/) that returns a JSON response.
• Structured using modules for configuration, routes, handlers, and models.

Modules

main.rs

The entry point of the application:

• Loads the server configuration.
• Initializes and starts the server with the specified host and port.

config.rs

Defines server configuration:

• Sets default values for the HOST and PORT.
• Provides a load function to initialize configuration.

server.rs

Server setup:

• Imports the home route and binds it to the server.
• Parses the IP address and port to run the Warp server.

routes/home.rs

Defines a route for the home path (/):

• Uses the hello_handler to respond with JSON data.

handlers/hello.rs

Handler for the home route:

• Returns a JSON response with a "ping" message.

models/response.rs

Defines the data model for the JSON response:

• Contains a single field, message, that will be serialized into JSON.

Running the Server

To start the server, run the following command:

cargo run

By default, the server will be available at http://127.0.0.1:8080.

API Endpoint

• GET / - Returns a JSON message confirming the route is reachable.

Example Response

{
  "message": "ping to hello_handler"
}

Dependencies

• Warp - For creating a lightweight, asynchronous web server.

• Serde - For serializing the JSON response.
