Struct AudioUnitParameter 

#[repr(C)]
pub struct AudioUnitParameter {
    pub mAudioUnit: *mut OpaqueAudioComponentInstance,
    pub mParameterID: u32,
    pub mScope: u32,
    pub mElement: u32,
}

An audio unit parameter is defined by the triplet of audio unit scope, element and parameterID. This struct is used with the functions in AudioUnitUtilities.h to deal with audio unit parameters, but is included in this header file for completeness.

The audio unit instance to which the specified parameter applies.

The parameterID for the parameter

The scope for the parameter

The element for the parameter

Trait Implementations

impl Clone for AudioUnitParameter

fn clone(&self) -> AudioUnitParameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AudioUnitParameter

impl Debug for AudioUnitParameter

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

Formats the value using the given formatter.

impl Encode for AudioUnitParameter

Available on crate feature AudioComponent only.

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for AudioUnitParameter

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