Enum HandlerResponse 

pub enum HandlerResponse {
    Sync(Result<Vec<u8>, Error>),
    Async(Pin<Box<dyn Future<Output = Result<Vec<u8>, Error>> + Send>>),
}

Response from a conduit command handler.

Sync handlers return Sync with the result immediately available. Async handlers return Async with a future that resolves to the response bytes.

Variants

Sync(Result<Vec<u8>, Error>)

Synchronous result, available immediately.

Async(Pin<Box<dyn Future<Output = Result<Vec<u8>, Error>> + Send>>)

Asynchronous result — a pinned future that resolves to the response.
