}Expand description
An HTTP request handler.
This trait is automatically implemented for Fn types, and so is rarely implemented
directly by Envoy users.
In practice, endpoints are functions that take a Request as an argument and
return a type T that implements Into<Response>.
Endpoints are implemented as asynchronous functions that make use of language features currently only available in Rust Nightly. For this reason, we have to explicitly enable the attribute will be omitted in most of the documentation.
A simple endpoint that is invoked on a GET request and returns a String:
async fn hello(ctx: &mut envoy::Context) -> envoy::Result {
Ok(ctx.res.set_body(String::from("hello")))
}
let mut app = envoy::Server::new();
app.at("/hello").get(hello);
