Rust SDK for Runtime.land.

This SDK is used to develop Runtime.land functions. It provides a set of methods to handle http request and response via land_sdk::http module on Runtime.land.

Hello World

use land_sdk::http::{Body, Error, Request, Response};
use land_sdk::http_main;

#[http_main]
pub fn handle_request(req: Request) -> Result<Response, Error> {
    // read uri and method from request
    let url = req.uri().clone();
    let method = req.method().to_string().to_uppercase();

    // build response
    Ok(http::Response::builder()
        .status(200)
        .header("X-Request-Url", url.to_string())
        .header("X-Request-Method", method)
        .body(Body::from("Hello Runtime.land!!"))
        .unwrap())
