Struct usb_util::device::TransferHandle

pub struct TransferHandle {
    weak_transfer: Weak<Transfer>,
    fd: Weak<File>,
}

Expand description

TransferHandle is a handle that allows cancellation of in-flight transfers between submit_transfer() and get_completed_transfer(). Attempting to cancel a transfer that has already completed is safe and will return an error.

Fields§

§weak_transfer: Weak<Transfer>§fd: Weak<File>

Implementations§

impl TransferHandle

pub fn cancel(&self) -> Result<()>

Attempt to cancel the transfer associated with this TransferHandle. Safe to call even if the transfer has already completed; Error::TransferAlreadyCompleted will be returned in this case.
