The FastEdge Rust SDK
Example of simple app with http entrypoint:
// lib.rs
use anyhow::Result;
use fastedge::http::{Request, Response, StatusCode};
use fastedge::body::Body;
#[fastedge::http]
fn main(req: Request<Body>) -> Result<Response<Body>> {
Response::builder().status(StatusCode::OK).body(Body::empty())
}
The important things to note in the function above:
- the
fastedge::httpmacro — this marks the function as the entrypoint for the FastEdge application - the function signature —
fn main(req: Request<Body>) -> Result<Response<Body>>— uses the HTTP objects from the popular Rust cratehttp
