Struct AudioHardwareIOProcStreamUsage 

#[repr(C)]
pub struct AudioHardwareIOProcStreamUsage {
    pub mIOProc: NonNull<c_void>,
    pub mNumberStreams: u32,
    pub mStreamIsOn: [u32; 1],
}

Available on crate feature AudioHardware only.

This structure describes which streams a given AudioDeviceIOProc will use. It is used in conjunction with kAudioDevicePropertyIOProcStreamUsage. Field: mIOProc The IOProc whose stream usage is being specified. Field: mNumberStreams The number of streams being specified. Field: mStreamIsOn An array of UInt32’s whose length is specified by mNumberStreams. Each element of the array corresponds to a stream. A value of 0 means the stream is not to be enabled. Any other value means the stream is to be used.

Trait Implementations

impl Clone for AudioHardwareIOProcStreamUsage

fn clone(&self) -> AudioHardwareIOProcStreamUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioHardwareIOProcStreamUsage

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

impl Encode for AudioHardwareIOProcStreamUsage

Available on crate feature objc2 only.

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for AudioHardwareIOProcStreamUsage

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