rweb

Yet another web server framework for rust.

Installation:

[dependencies]
rweb = "0.6"
tokio = "1"

Installation (with automatic openapi generation):

[dependencies]
rweb = { version = "0.6", features = ["openapi"] }
serde = "1"
tokio = "1"

Features

• Safe & Correct

Since rweb is based on warp, which features safety and correctness, rweb has same property.

• Easy to read code

use rweb::*;
use serde::{Serialize, Deserialize};

#[get("/output")]
fn output() -> String {
    String::from("this returns 200 with text/plain mime type")
}

#[derive(Debug, Serialize, Deserialize, Schema)]
struct Product {
    id: String,
    title: String,
}

#[get("/products")]
fn products() -> Json<Vec<Product>> {
    // ...
    // This returns 200 with application/json
}

#[get("/products/{id}")]
fn product(id: String) -> Json<Product> {
    // ...
    // This returns 200 with application/json
}

#[get("/product")]
fn new_product(_product: Json<Product>) -> Json<Product> {
    // ...
    // This returns 200 with application/json
}

#[derive(Debug, Serialize, Deserialize, Schema)]
struct SearchOption {
    query: String,
    limit: usize,
    page_token: String,
}

#[get("/search")]
fn search(_product: Query<SearchOption>) -> Json<Vec<Product>> {
    // ...
    // This returns 200 with application/json
}

#[tokio::main]
async fn main() {
    serve(output().or(product()).or(products()).or(search())).run(([127, 0, 0, 1], 3030)).await;
}

• Websocket

If you want to use websocket, just declare a parameter typed Ws. It's all.

use rweb::*;

#[get("/ws")]
fn example(ws: ws::Ws) -> String {
    String::new("use ws.on_upgrade or extra")
}

• Automatic openapi spec generation

rweb supports automatically generating openapi specification file based on your code.

See: documentation for usage.

• API UX interaction for openapi

// Build openapi for your API
let (spec, filter) = openapi::spec().build(move || {
    // Your API's filters
    math::math()
        .or(products::products())
        .or(generic::body())
        .or(generic::optional())
        .or(generic::search())
        .or(response::response())
});

println!("go to http://localhost:3030/docs to interact with your openapi!");
serve(filter.or(openapi_docs(spec)))
    .run(([127, 0, 0, 1], 3030))
    .await;
