Crate fastrust 

fastrust - A FastAPI-inspired web framework for building APIs in Rust.

fastrust provides a simple, intuitive API for building web services with automatic OpenAPI 3.0 specification generation and Swagger UI support.

Example

use fastrust::{APIApp, APIRouter, RouteConfig};
use axum::extract::Path;

async fn hello(Path(name): Path<String>) -> String {
    format!("Hello {}\n", name)
}

#[tokio::main]
async fn main() {
    let mut api = APIRouter::new("/api");
    api.get("/hello/{name}", hello, RouteConfig::default());

    APIApp::new()
        .set_title("My API")
        .set_port(8080)
        .register_router(api)
        .run().await;
}

Features

• FastAPI-inspired API design
• Automatic OpenAPI 3.0 specification generation
• Built-in Swagger UI at /docs
• Type-safe request/response schemas via schemars
• Built on top of axum
