Struct AudioSourceControlHandler 

pub struct AudioSourceControlHandler { /* private fields */ }

Implementation of the logic for Audio Control requests (e.g., volume, mute)

Implementations

impl AudioSourceControlHandler

pub fn new( sample_rates: &'static [u32], ep_audio_addr: EndpointAddress, ep_feedback_addr: EndpointAddress, iface_ctrl_num: InterfaceNumber, iface_stream_num: InterfaceNumber, ) -> Self

Create a new AudioSourceControlHandler

pub fn get_audio_ep_addr(&self) -> u8

Gets the audio endpoint address

pub fn get_feedback_ep_addr(&self) -> u8

Gets the feedback endpoint address

pub fn get_audio_ep_index(&self) -> usize

Gets the index part of the audio endpoint address

pub fn get_feedback_ep_index(&self) -> usize

Gets the index part of the feedback endpoint address

pub fn get_ctrl_iface_num(&self) -> u8

Gets the bInterfaceNumber of the control interface

pub fn get_stream_iface_num(&self) -> u8

Gets the bInterfaceNumber of the streaming interface

Trait Implementations

impl<'d> Handler for AudioSourceControlHandler

fn addressed(&mut self, addr: u8)

Called when the host has set the address of the device to addr.

fn configured(&mut self, configured: bool)

Called when the host has enabled or disabled the configuration of the device.

fn remote_wakeup_enabled(&mut self, enabled: bool)

Called when remote wakeup feature is enabled or disabled.

fn set_alternate_setting( &mut self, iface: InterfaceNumber, alternate_setting: u8, )

Called when a “set alternate setting” control request is done on the interface.

fn reset(&mut self)

Called after a USB reset after the bus reset sequence is complete.

fn suspended(&mut self, suspended: bool)

Called when the bus has entered or exited the suspend state.

fn control_out(&mut self, req: Request, buf: &[u8]) -> Option<OutResponse>

Called when a control request is received with direction HostToDevice.

fn control_in<'a>( &'a mut self, req: Request, buf: &'a mut [u8], ) -> Option<InResponse<'a>>

Called when a control request is received with direction DeviceToHost.

fn enabled(&mut self, _enabled: bool)

Called when the USB device has been enabled or disabled.

fn get_string(&mut self, index: StringIndex, lang_id: u16) -> Option<&str>

Called when a GET_DESCRIPTOR STRING control request is received.

fn get_descriptor_requested( &mut self, _descriptor_type: u8, _index: u8, _wlength: u16, )

Called when a GET_DESCRIPTOR control request is received, before the descriptor is sent.
