Struct near_async::messaging::MessageWithCallback

pub struct MessageWithCallback<T, R> {
    pub message: T,
    pub callback: Box<dyn FnOnce(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 function (which resolves the future that send_async returns).

Fields

message: T

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