Expand description

Implement this trait to create a view.

A view is a collection of methods that are called when a request is made to a specific route.

The methods are called based on the HTTP method of the request. For example, if a request is made to a route with a GET method, the get method will be called.

If a method is not implemented, a 405 Method Not Allowed response will be returned.

Example

#[derive(Debug)]
pub struct HelloView;

#[async_trait::async_trait]
impl View for HelloView {
    async fn get(&self, request: Request<Body>) -> Result<Response<Body>> {
        Ok(Response::builder()
            .status(StatusCode::OK)
            .body(Body::from("Say hello to Swim!"))
            .unwrap())
    }
}
