• Built-in DoS/DDoS protection - enabled by default, with no performance penalty.
• Fully configurable limits and timeouts for requests, responses, and connections.
• Custom connection filtering - implement the ConnectionFilter trait to reject unwanted connections at the TCP level.

• Zero-allocation - no memory allocations after server startup.
• Pre-allocated memory for each connection - linear and transparent scaling.

• Full HTTP stack - HTTP/1.1, HTTP/1.0, HTTP/0.9+ with keep-alive.
• Automatic protocol detection for each request - keep-alive eliminates the need for manual protocol selection.
• Storing data between requests - ability to store data between requests in a single connection using the [ConnectionData] trait.

• Graceful performance degradation - automatic 503 responses when overloaded.
• Custom error format - structured JSON (with codes/descriptions) or a plain HTTP response.
• Resource protection - automatic closure of connections exceeding set limits.

• High-throughput microservices - configurable for specific workloads
• Resource-constrained environments - predictable memory usage
• Internal APIs - security-conscious defaults
• Performance-critical applications - zero-allocation design
• Legacy system integration - HTTP/1.0 compatibility

Everything that remains outside the documentation—live statistics, deep details, and informal plans—I collect on a separate website. This is a space that I strive to keep current and meaningful.

Add maker_web and tokio to your Cargo.toml:

cargo add maker_web tokio --features tokio/full

Or manually:

[dependencies]
maker_web = "0.1"
tokio = { version = "1", features = ["full"] }

use maker_web::{Handled, Handler, Request, Response, Server, StatusCode};
use tokio::net::TcpListener;

struct MyHandler;

impl Handler for MyHandler {
    async fn handle(&self, _: &mut (), req: &Request, resp: &mut Response) -> Handled {
        match req.url().path_segments_str() {
            ["api", user, "name"] => {
                resp.status(StatusCode::Ok).body(user)
            }
            ["api", user, "name", "len"] => {
                resp.status(StatusCode::Ok).body(user.len())
            }
            ["api", "echo", text] => {
                resp.status(StatusCode::Ok).body(text)
            }
            _ => resp.status(StatusCode::NotFound).body("qwe"),
        }
    }
}

#[tokio::main]
async fn main() {
    Server::builder()
        .listener(TcpListener::bind("127.0.0.1:8080").await.unwrap())
        .handler(MyHandler)
        .build()
        .launch()
        .await;
}
