speed-rs-core

A core HTTP Server implementation for Rust.

Installation

Create a new Rust project using cargo

cargo new your-project

Add the package to your project

cargo add speed-rs-core

Or add the following line to the dependencies in your Cargo.toml file:

[dependencies]
...
speed-rs-core = "0.4.1"

Finally build the project

cargo build

Now you can use the package freely.

How To Use

speed-rs-core provides just the core HTTP handling, so you will need to handle the higher-level abstractions. Below is an example of how to respond with an HTML file to the client when there is a request:

use std::fs;
use speed_rs_core::{HttpServer, HttpServerMode, HttpStatusStruct};

fn main() {
    // Create the server in single-thread mode
    let mut server = HttpServer::new(HttpServerMode::SingleThread, "127.0.0.1:3000");
    
    // Provide the request handling function
    server.insert_handler(|mut req, mut res| {
        res.set_status(HttpStatusStruct(200, "OK"));
        res.insert_header("Content-Type".to_string(), "text/html".to_string());


        // Read the HTML
        let err = match fs::read_to_string("public/index.html") {
            Ok(html) => {
                res.text(html);
                None
            },
            Err(e) => Some(e)
        };

        // Since the ownership of req and res are taken, you must return them back to the server
        if let Some(e) = err { Err((req, res, Box::new(e))) } else { Ok((req, res)) }
    });

    // Start listening for requests
    server.listen(|| {
        println!("Server is listening at http://127.0.0.1:3000");
    });
}

Development Guide

To further develop this package and leverage the powerful features of Rust, you can implement traits like RequestParamsExtractor for additional functionalities:

use std::collections::HashMap;
use speed_rs_core::HttpRequest;

trait RequestParamsExtractor {
    fn params(&self) -> HashMap<String, String>;
}

impl RequestParamsExtractor for HttpRequest {
    fn params(&self) -> HashMap<String, String> {
        // Implementation code here
        HashMap::new()
    }
}

// In your server's request handler
server.insert_handler(|mut req, mut res| {
    // ...
    let params = req.params();
    // ...
    Ok((req, res))
});
