Available on crate feature USB only.

Parameter block for control requests with timeouts, using a simple pointer for the data to be transferred. Same as a IOUSBDevRequest except for the two extra timeout fields. Field: bmRequestType Request type: kUSBStandard, kUSBClass or kUSBVendor Field: bRequest Request code Field: wValue 16 bit parameter for request, host endianess Field: wIndex 16 bit parameter for request, host endianess Field: wLength Length of data part of request, 16 bits, host endianess Field: pData Pointer to data for request - data returned in bus endianess Field: wLenDone Set by standard completion routine to number of data bytes actually transferred Field: noDataTimeout Specifies a time value in milliseconds. Once the request is queued on the bus, if no data is transferred in this amount of time, the request will be aborted and returned. Field: completionTimeout Specifies a time value in milliseconds. Once the request is queued on the bus, if the entire request is not completed in this amount of time, the request will be aborted and returned

impl Encode for IOUSBDevRequestTO

Available on crate features usb and objc2 only.

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for IOUSBDevRequestTO

Available on crate feature usb only.

fn eq(&self, other: &IOUSBDevRequestTO) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
