Struct cubeb_backend::DeviceInfoRef

pub struct DeviceInfoRef(_);

Implementations

impl DeviceInfoRef

pub unsafe fn from_ptr<'a>(ptr: *mut cubeb_device_info) -> &'a DeviceInfoRef

Safety

This function is unsafe because it dereferences the given ptr pointer. The caller should ensure that pointer is valid.

pub unsafe fn from_ptr_mut<'a>(
    ptr: *mut cubeb_device_info
) -> &'a mut DeviceInfoRef

Safety

This function is unsafe because it dereferences the given ptr pointer. The caller should ensure that pointer is valid.

pub fn as_ptr(&self) -> *mut cubeb_device_info

impl DeviceInfoRef

pub fn devid(&self) -> *const c_void

Device identifier handle.

pub fn device_id(&self) -> Option<&str>

Device identifier which might be presented in a UI.

pub fn device_id_bytes(&self) -> Option<&[u8]>

pub fn friendly_name(&self) -> Option<&str>

Friendly device name which might be presented in a UI.

pub fn friendly_name_bytes(&self) -> Option<&[u8]>

pub fn group_id(&self) -> Option<&str>

Two devices have the same group identifier if they belong to the same physical device; for example a headset and microphone.

pub fn group_id_bytes(&self) -> Option<&[u8]>

pub fn vendor_name(&self) -> Option<&str>
