Struct CoreAudioDevice 

pub struct CoreAudioDevice { /* private fields */ }

SIM-visible CoreAudio device metadata.

Implementations

impl CoreAudioDevice

pub fn output( id: impl Into<String>, name: impl Into<String>, channels: usize, timing: CoreAudioTiming, ) -> Result<Self>

Builds an output-direction device. See CoreAudioDevice::new.

pub fn input( id: impl Into<String>, name: impl Into<String>, channels: usize, timing: CoreAudioTiming, ) -> Result<Self>

Builds an input-direction device. See CoreAudioDevice::new.

pub fn duplex( id: impl Into<String>, name: impl Into<String>, channels: usize, timing: CoreAudioTiming, ) -> Result<Self>

Builds a duplex (input and output) device. See CoreAudioDevice::new.

pub fn new( id: impl Into<String>, name: impl Into<String>, direction: HostDirection, channels: usize, timing: CoreAudioTiming, ) -> Result<Self>

Builds a device from its id, display name, direction, channel count, and timing.

The device starts flagged as neither the default input nor the default output. Returns an error when channels is zero.

pub fn with_default_output(self) -> Self

Returns this device flagged as the default output device.

pub fn with_default_input(self) -> Self

Returns this device flagged as the default input device.

pub fn id(&self) -> &Symbol

Returns the device’s identifying symbol.

pub fn name(&self) -> &str

Returns the device’s human-readable display name.

pub fn direction(&self) -> HostDirection

Returns the device’s I/O direction.

pub fn channels(&self) -> usize

Returns the device’s channel count.

pub fn timing(&self) -> CoreAudioTiming

Returns the device’s timing metadata.

pub fn default_output(&self) -> bool

Returns whether this device is flagged as the default output.

pub fn default_input(&self) -> bool

Returns whether this device is flagged as the default input.

pub fn spec(&self) -> Result<PcmSpec>

Returns the f32 PCM spec for this device’s channels and sample rate.

pub fn is_compatible_with(&self, requested: HostDirection) -> bool

Returns whether this device can serve a stream in the requested direction.

A duplex device is compatible with any requested direction.

pub fn port_symbol(&self) -> Symbol

Returns the <id>/port symbol naming this device’s host port.

pub fn backend(&self) -> Symbol

Returns the CoreAudio backend symbol this device belongs to.

Trait Implementations

impl Clone for CoreAudioDevice

fn clone(&self) -> CoreAudioDevice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoreAudioDevice

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

Formats the value using the given formatter.

impl Eq for CoreAudioDevice

impl PartialEq for CoreAudioDevice

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