Struct AVCaptureExposureMode 

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

Available on crate feature AVCaptureDevice only.

Constants indicating the mode of the exposure on the receiver’s device, if it has adjustable exposure.

Indicates that the exposure should be locked at its current value.

Indicates that the device should automatically adjust exposure once and then change the exposure mode to AVCaptureExposureModeLocked.

Indicates that the device should automatically adjust exposure when needed.

Indicates that the device should only adjust exposure according to user provided ISO, exposureDuration values.

Trait Implementations

impl Clone for AVCaptureExposureMode

fn clone(&self) -> AVCaptureExposureMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AVCaptureExposureMode

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

Formats the value using the given formatter.

impl Encode for AVCaptureExposureMode

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AVCaptureExposureMode

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 AVCaptureExposureMode

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

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

fn partial_cmp(&self, other: &AVCaptureExposureMode) -> 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 AVCaptureExposureMode

const ENCODING_REF: Encoding

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

impl Copy for AVCaptureExposureMode

impl Eq for AVCaptureExposureMode

impl StructuralPartialEq for AVCaptureExposureMode
