This project is a simple HTTP server implemented in Rust using the standard library (std). It creates a thread pool to handle incoming TCP connections concurrently. Below is an explanation of the code:
The initial part of the code imports necessary modules and defines the main function.
std::fs: Filesystem operations.std::io::prelude::*: I/O traits and utilities.std::net::TcpListener: TCP listener for incoming connections.std::net::TcpStream: TCP stream for reading/writing data.std::thread: Thread-related functionalities.std::time::Duration: Time-related utilities.server::ThreadPool: Custom thread pool implementation.
- Binds the server to
127.0.0.1:7878. - Creates a thread pool with 4 threads (
ThreadPool::new(4)). - Accepts incoming TCP connections in a loop and dispatches them to the thread pool for handling (
pool.execute(|| { handle_connection(stream); });).
Handles each TCP connection.
- Reads data from the client into a buffer.
- Parses the HTTP request to determine the requested resource.
- Generates an appropriate HTTP response based on the request.
Defines a custom thread pool (struct ThreadPool) to manage worker threads.
- Uses a message passing mechanism (
mpsc::channel) to communicate between the main thread and worker threads. - Workers (
struct Worker) listen for incoming jobs (closures) and execute them concurrently.
