Implementations

impl ARTrackingStateReason

pub const None: Self

Tracking is not limited.

pub const Initializing: Self

Tracking is limited due to initialization in progress.

pub const ExcessiveMotion: Self

Tracking is limited due to a excessive motion of the camera.

pub const InsufficientFeatures: Self

Tracking is limited due to a lack of features visible to the camera.

pub const Relocalizing: Self

Tracking is limited due to a relocalization in progress.

Trait Implementations

impl Clone for ARTrackingStateReason

fn clone(&self) -> ARTrackingStateReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ARTrackingStateReason

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

Formats the value using the given formatter.

impl Encode for ARTrackingStateReason

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for ARTrackingStateReason

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 ARTrackingStateReason

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

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

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

const ENCODING_REF: Encoding

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

impl Copy for ARTrackingStateReason

impl Eq for ARTrackingStateReason
