Struct Callback 

pub struct Callback<T> {
    pub callback_id: String,
    /* private fields */
}

A callback handle that can be used to wait for external signals.

The callback ID can be shared with external systems, which can then signal completion by calling the Lambda durable execution callback API.

Fields

callback_id: String
