Struct Device 

pub struct Device { /* private fields */ }

Struct wrapping an IMMDevice.

Implementations

impl Device

pub unsafe fn from_raw(device: IMMDevice, direction: Direction) -> Device

Build a Device from a supplied [IMMDevice] and Direction

Safety

The caller must ensure that the [IMMDevice]’s data flow direction is the same as the Direction supplied to the function.

Use Device::from_immdevice, which queries the endpoint, for safe construction.

pub fn from_immdevice(device: IMMDevice) -> Result<Device, WasapiError>

Attempts to build a Device from a supplied [IMMDevice], querying the endpoint for its data flow direction.

pub fn get_iaudioclient(&self) -> Result<AudioClient, WasapiError>

Get an [IAudioClient] from an [IMMDevice]

pub fn get_iaudiosessionmanager( &self, ) -> Result<AudioSessionManager, WasapiError>

Gets an [IAudioSessionManager] from an [IMMDevice]

pub fn get_state(&self) -> Result<DeviceState, WasapiError>

Read state from an [IMMDevice]

pub fn get_friendlyname(&self) -> Result<String, WasapiError>

Read the friendly name of the endpoint device (for example, “Speakers (XYZ Audio Adapter)”)

pub fn get_interface_friendlyname(&self) -> Result<String, WasapiError>

Read the friendly name of the audio adapter to which the endpoint device is attached (for example, “XYZ Audio Adapter”)

pub fn get_description(&self) -> Result<String, WasapiError>

Read the device description of the endpoint device (for example, “Speakers”)

pub fn get_device_format(&self) -> Result<WaveFormat, WasapiError>

Read the device format of the endpoint device, which is the format that the user has selected for the stream that flows between the audio engine and the audio endpoint device when the device operates in shared mode.

pub fn get_id(&self) -> Result<String, WasapiError>

Get the Id of an [IMMDevice]

pub fn get_direction(&self) -> Direction

Get the direction for this Device
