Struct AVCaptureDevicePosition

#[repr(transparent)]
pub struct AVCaptureDevicePosition(pub NSInteger);

Available on crate feature AVCaptureDevice only.

Constants indicating the physical position of an AVCaptureDevice’s hardware on the system.

Indicates that the device’s position relative to the system hardware is unspecified.

Indicates that the device is physically located on the back of the system hardware.

Indicates that the device is physically located on the front of the system hardware.

Trait Implementations

impl Clone for AVCaptureDevicePosition

fn clone(&self) -> AVCaptureDevicePosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AVCaptureDevicePosition

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

Formats the value using the given formatter.

impl Encode for AVCaptureDevicePosition

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AVCaptureDevicePosition

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 AVCaptureDevicePosition

fn cmp(&self, other: &AVCaptureDevicePosition) -> 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 AVCaptureDevicePosition

fn eq(&self, other: &AVCaptureDevicePosition) -> 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 AVCaptureDevicePosition

fn partial_cmp(&self, other: &AVCaptureDevicePosition) -> 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.

impl RefEncode for AVCaptureDevicePosition

const ENCODING_REF: Encoding

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

impl Copy for AVCaptureDevicePosition

impl Eq for AVCaptureDevicePosition
