Introduction

In this article, we will explore the implementation of an embedded HTTPS server using the Tokio framework in Rust. The server will handle HTTP/HTTPS requests asynchronously and support TLS encryption for secure communication. We will utilize the Tokio runtime for asynchronous operations, Hyper for HTTP server functionality, and Rustls for TLS encryption.

Requirements

Utilize the Tokio Runtime

The Tokio runtime is a popular choice for building asynchronous applications in Rust. It provides a high-level API for writing asynchronous code and integrates well with other popular libraries.

Use Hyper for HTTP Server Functionality

Hyper is a popular HTTP server library for Rust that provides a simple and efficient way to handle HTTP requests. We will use Hyper to handle HTTP requests and integrate it with the Tokio runtime.

Integrate Rustls for TLS Encryption

Rustls is a modern TLS library for Rust that provides a simple and efficient way to implement TLS encryption. We will use Rustls to integrate TLS encryption with our embedded HTTPS server.

Support Routing for Handling Different API Endpoints

Routing is an essential feature for any web server, allowing it to handle different API endpoints and return the correct response. We will use the Hyper routing API to handle different API endpoints.

Provide Basic Logging and Error Handling

Logging and error handling are crucial features for any web server, allowing it to handle errors and provide useful logs for debugging. We will use the Tokio logging API to provide basic logging and error handling.

OpenTelemetry Support

OpenTelemetry is a popular observability library that provides a simple and efficient way to collect metrics and logs from applications. We will use OpenTelemetry to integrate metrics and logs with our embedded HTTPS server.

Write Unit Tests to Ensure Stability

Unit tests are essential for ensuring the stability of any web server. We will write unit tests to ensure that our embedded HTTPS server handles different scenarios correctly.

Implementation

Step 1: Add Dependencies

First, we need to add the required dependencies to our Cargo.toml file:

[dependencies]
tokio = { version = "1", features = ["full"] }
hyper = "0.14.20"
hyper-tls = "0.4.18"
rustls = "0.20.0"
tokio-tls = "0.4.0"
opentelemetry = "0.14.0"
opentelemetry-otlp = "0.14.0"

Step 2: Create the Embedded HTTPS Server

Next, we will create the embedded HTTPS server using the Tokio framework:
