Struct AudioHardwarePowerHint 

#[repr(transparent)]
pub struct AudioHardwarePowerHint(pub u32);

Available on crate feature AudioHardware only.

The values for kAudioHardwarePropertyPowerHint

The system object property, kAudioHardwarePropertyPowerHint, allows a process to to indicate how aggressive the system can be with optimizations that save power. Note that the value of this property can be set in an application’s info.plist using the key, “AudioHardwarePowerHint”. The values for this key are the strings that correspond to the values in the enum.

This is the default value and it indicates that the system will not make any power optimizations that compromise latency or quality in order to save power. The info.plist value is “None” or the “AudioHardwarePowerHint” entry can be omitted entirely.

The system will choose to save power even at the expense of latency. The info.plist value is “Favor Saving Power”

impl Ord for AudioHardwarePowerHint

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

impl PartialEq for AudioHardwarePowerHint

fn eq(&self, other: &AudioHardwarePowerHint) -> 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.

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