Struct IOUSBHostIOSourceDescriptors 

#[repr(C)]
pub struct IOUSBHostIOSourceDescriptors {
    pub bcdUSB: u16,
    pub descriptor: IOUSBEndpointDescriptor,
    pub ssCompanionDescriptor: IOUSBSuperSpeedEndpointCompanionDescriptor,
    pub sspCompanionDescriptor: IOUSBSuperSpeedPlusIsochronousEndpointCompanionDescriptor,
}

Available on crate features IOUSBHostIOSource and objc2-io-kit only.

Encapsulates descriptors for a single endpoint

The IOUSBHostIOSourceDescriptors struct is used to initialize and adjust pipes in the system. The bcdUSB member must be initialized to the USB revision supported by the device. Acceptable values are 0x0110, 0x0200, 0x0300, 0x0310. The descriptor member must always be initialized with a valid endpoint descriptor. The ssCompanionDescriptor and sspCompanionDescriptor members may be required for bcdUSB versions 0x0300 and greater, depending on device operating speed and values set in the descriptors. See USB 3.1 § 9.5 for more information on when these descriptors may be required.

Trait Implementations

impl Clone for IOUSBHostIOSourceDescriptors

fn clone(&self) -> IOUSBHostIOSourceDescriptors

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IOUSBHostIOSourceDescriptors

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Encode for IOUSBHostIOSourceDescriptors

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for IOUSBHostIOSourceDescriptors

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

impl RefEncode for IOUSBHostIOSourceDescriptors

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.
