Struct AudioLevelControlTransferFunction 

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

Available on crate feature AudioHardwareDeprecated only.

The following constants are the only supported values for a volume control’s transfer function.

The transfer function implemented in the volume control works by raising the scalar value to an exponent to map it into the decibel range. The constants in this enum express the exponent used in the name as a quotient. For example, kAudioLevelControlTranferFunction3Over4 represents the exponent 0.75.

Trait Implementations

impl Clone for AudioLevelControlTransferFunction

fn clone(&self) -> AudioLevelControlTransferFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioLevelControlTransferFunction

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

Formats the value using the given formatter.

impl Encode for AudioLevelControlTransferFunction

Available on crate feature objc2 only.

const ENCODING: Encoding = u32::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AudioLevelControlTransferFunction

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 AudioLevelControlTransferFunction

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

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