Struct IOUSBHostCIDeviceState 

#[repr(transparent)]
pub struct IOUSBHostCIDeviceState(pub c_uint);

Available on crate feature IOUSBHostControllerInterfaceDefinitions only.

Device state managed by IOUSBHostCIDeviceStateMachine

IOUSBHostCIDeviceStateDestroyed represents a device that is no longer usable, and whose resources will be destroyed and freed IOUSBHostCIDeviceStatePaused represents a device that may have IO requests enqueued, but they are not active on the bus. The state is closely correlated to IOUSBHostCIPortStateSuspended, and endpoints associated with this device may not be in the IOUSBHostCIEndpointStateActive state. IOUSBHostCIDeviceStateActive is the initial sate of a newly created IOUSBHsotCIDeviceStateMachine, and represents a device that can be processing IO requests. Endpoints associated with this device may be in the IOUSBHostCIEndpointStateActive state.

Trait Implementations

impl Clone for IOUSBHostCIDeviceState

fn clone(&self) -> IOUSBHostCIDeviceState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IOUSBHostCIDeviceState

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

Formats the value using the given formatter.

impl Encode for IOUSBHostCIDeviceState

const ENCODING: Encoding = c_uint::ENCODING

The Objective-C type-encoding for this type.

impl Hash for IOUSBHostCIDeviceState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for IOUSBHostCIDeviceState

fn cmp(&self, other: &IOUSBHostCIDeviceState) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IOUSBHostCIDeviceState

fn eq(&self, other: &IOUSBHostCIDeviceState) -> 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 PartialOrd for IOUSBHostCIDeviceState

fn partial_cmp(&self, other: &IOUSBHostCIDeviceState) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
