Struct AVCaptureOutputDataDroppedReason

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

Available on crate feature AVCaptureOutputBase only.

Constants indicating the reason a capture data output dropped data.

No data was dropped.

Data was dropped because alwaysDiscardsLate{VideoFrames | DepthData} is YES and the client was still processing previous data when the current data needed to be delivered.

Data was dropped because its pool of buffers ran dry. This is usually indicative that the client is holding onto data objects too long.

Data was dropped because the device providing the data experienced a discontinuity, and an unknown number of data objects have been lost. This condition is typically caused by the system being too busy.

Trait Implementations

impl Clone for AVCaptureOutputDataDroppedReason

fn clone(&self) -> AVCaptureOutputDataDroppedReason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AVCaptureOutputDataDroppedReason

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

Formats the value using the given formatter.

impl Encode for AVCaptureOutputDataDroppedReason

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AVCaptureOutputDataDroppedReason

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 AVCaptureOutputDataDroppedReason

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

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

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