Attribute Macro openapi 

#[openapi]

A proc macro to be used in tandem with one of Rocket’s endpoint macros. It requires that all of the arguments of the route implement one of the traits in rocket_autodocu::request, and that the return type implements OpenApiResponder.

Example

use rocket_autodocu::openapi;
use rocket::get;

#[openapi]
#[get("/hello/<number>")]
fn hello_world(number: i32) -> String {
    format!("Hello world number {}", number)
}
