Struct IOUSBLowLatencyIsocFrame 

#[repr(C)]
pub struct IOUSBLowLatencyIsocFrame {
    pub frStatus: IOReturn,
    pub frReqCount: u16,
    pub frActCount: u16,
    pub frTimeStamp: i32,
}

Available on crate feature USB only.

Structure used to encode information about each isoc frame that is processed at hardware interrupt time (low latency).

Parameter frStatus: Returns status associated with the frame.

Parameter frReqCount: Input specifiying how many bytes to read or write.

Parameter frActCount: Actual # of bytes transferred.

Parameter frTimeStamp: Time stamp that indicates time when frame was procesed.

Trait Implementations

impl Clone for IOUSBLowLatencyIsocFrame

Available on crate feature usb only.

fn clone(&self) -> IOUSBLowLatencyIsocFrame

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IOUSBLowLatencyIsocFrame

Available on crate feature usb only.

Formats the value using the given formatter.

impl Encode for IOUSBLowLatencyIsocFrame

Available on crate features usb and objc2 only.

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for IOUSBLowLatencyIsocFrame

Available on crate feature usb only.

fn eq(&self, other: &IOUSBLowLatencyIsocFrame) -> 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.
