Struct nusb::transfer::TransferFuture

pub struct TransferFuture<D: TransferRequest> { /* private fields */ }

Future used to await the completion of a transfer.

Use the methods on Interface to submit an individual transfer and obtain a TransferFuture.

The transfer is cancelled on drop. The buffer and any partially-completed data are destroyed. This means that TransferFuture is not cancel-safe and cannot be used in select!{}, When racing a TransferFuture with a timeout you cannot tell whether data may have been partially transferred on timeout. Use the Queue interface if these matter for your application.
