Struct MessageWithCallback

pub struct MessageWithCallback<T, R> {
    pub message: T,
    pub callback: Box<dyn FnOnce(BoxFuture<'static, Result<R, AsyncSendError>>) + Send>,
}

Used to implement an async sender. An async sender is just a Sender whose message is MessageWithCallback<M, R>, which is a message plus a callback to send the response future back.

Fields

message: T

callback: Box<dyn FnOnce(BoxFuture<'static, Result<R, AsyncSendError>>) + Send>
