Implementations

impl<T> QueryResponseFut<T>

pub fn check(self) -> Result<Self, Error>

Check to see if the query has an error. If there was en error sending, this returns it and the error is returned, otherwise it returns self, which can then be awaited on: i.e. match echo_proxy.echo(“something”).check() { Err(e) => error!(“Couldn’t send: {}”, e), Ok(fut) => fut.await }
