Struct usb_util::Transfer

pub struct Transfer {
    urb: Vec<usbdevfs_urb>,
    pub buffer: TransferBuffer,
    callback: Option<Box<dyn Fn(Transfer) + Send + Sync>>,
}

Transfer contains the information necessary to submit a USB request and, once it has been submitted and completed, contains the response.

Fields

urb: Vec<usbdevfs_urb>

buffer: TransferBuffer

callback: Option<Box<dyn Fn(Transfer) + Send + Sync>>

Implementations
