Trait seamless::handler::response::HandlerResponse

pub trait HandlerResponse {
    type ResponseBody: ApiBody;

    fn handler_response<'async_trait>(
        self
    ) -> Pin<Box<dyn Future<Output = Result<Response<Vec<u8>>, ApiError>> + Send + 'async_trait>>
    where
        Self: 'async_trait;
}

Anything that you’d like to be able to return from a handler function must implement this trait, which decides how to take the result of a handler function and encode it into an http::Response<Vec<u8>>, or failing to do so, returns an ApiError.

Required Associated Types

type ResponseBody: ApiBody

The type that we should look at to work out what the response body will look like.

Required Methods

fn handler_response<'async_trait>(
    self
) -> Pin<Box<dyn Future<Output = Result<Response<Vec<u8>>, ApiError>> + Send + 'async_trait>>where
    Self: 'async_trait,

This describes how the type can be converted into an http::Response.
