Struct cubeb_backend::ContextRef

pub struct ContextRef(_);

Implementations

impl ContextRef

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

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) -> &'a mut ContextRef

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

impl ContextRef

pub fn backend_id(&self) -> &str

pub fn backend_id_bytes(&self) -> &[u8]

pub fn max_channel_count(&self) -> Result<u32, Error>

pub fn min_latency(&self, params: &StreamParamsRef) -> Result<u32, Error>

pub fn preferred_sample_rate(&self) -> Result<u32, Error>

pub unsafe fn stream_init(
    &self,
    stream_name: Option<&CStr>,
    input_device: *const c_void,
    input_stream_params: Option<&StreamParamsRef>,
    output_device: *const c_void,
    output_stream_params: Option<&StreamParamsRef>,
    latency_frames: u32,
    data_callback: Option<unsafe extern "C" fn(*mut cubeb_stream, *mut c_void, *const c_void, *mut c_void, i64) -> i64>,
    state_callback: Option<unsafe extern "C" fn(*mut cubeb_stream, *mut c_void, u32)>,
    user_ptr: *mut c_void
) -> Result<Stream, Error>

Safety

This function is unsafe because it dereferences the given data_callback, state_callback, and user_ptr pointers. The caller should ensure those pointers are valid.

pub fn enumerate_devices(
    &self,
    devtype: DeviceType
) -> Result<DeviceCollection<'_>, Error>

pub unsafe fn register_device_collection_changed(
    &self,
    devtype: DeviceType,
    callback: Option<unsafe extern "C" fn(*mut cubeb, *mut c_void)>,
    user_ptr: *mut c_void
) -> Result<(), Error>

Safety

This function is unsafe because it dereferences the given callback and user_ptr pointers. The caller should ensure those pointers are valid.

Trait Implementations

impl AsRef<ContextRef> for Context

fn as_ref(&self) -> &ContextRef

impl Borrow<ContextRef> for Context

fn borrow(&self) -> &ContextRef

Immutably borrows from an owned value.

impl Debug for ContextRef

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