Implementations

impl AVExternalSyncDeviceStatus

pub const Unavailable: Self

Indicates that external sync signal is not connected, or has transitioned to a state that is not recoverable.

pub const Ready: Self

Indicates that a device supporting external sync is connected, but calibration has not started.

pub const Calibrating: Self

Indicates that the external sync signal is connected and that the AVExternalSyncDevice object is calibrating to follow.

pub const ActiveSync: Self

Indicates that the AVExternalSyncDevice object is running and that the clock property on AVExternalSyncDevice is calibrated to the external sync signal.

pub const FreeRunSync: Self

Indicates that the AVExternalSyncDevice was calibrated to follow the external sync, but the sync signal has been lost. The camera will continue to match the last signal it received, but sync is not guaranteed.

Trait Implementations

impl Clone for AVExternalSyncDeviceStatus

fn clone(&self) -> AVExternalSyncDeviceStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AVExternalSyncDeviceStatus

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

Formats the value using the given formatter.

impl Encode for AVExternalSyncDeviceStatus

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AVExternalSyncDeviceStatus

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,

impl Ord for AVExternalSyncDeviceStatus

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

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

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