Struct AUParameterAutomationEventType

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

Available on crate feature AUParameters only.

Identifies the different types of parameter automation events.

Audio Units may generate parameter changes from their user interfaces. Hosts may attach significance to the beginning and end of a UI gesture (typically touching and releasing a fader). These gestures are conveyed through these types of automation events.

The event contains an updated value for the parameter.

The event marks an initial “touch” gesture on a UI element.

The event marks a final “release” gesture on a UI element.

Trait Implementations

impl Clone for AUParameterAutomationEventType

fn clone(&self) -> AUParameterAutomationEventType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AUParameterAutomationEventType

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

Formats the value using the given formatter.

impl Encode for AUParameterAutomationEventType

const ENCODING: Encoding = u32::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AUParameterAutomationEventType

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 AUParameterAutomationEventType

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

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

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

const ENCODING_REF: Encoding

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