Struct libpulse_binding::context::ext_device_restore::DeviceRestore

pub struct DeviceRestore { /* fields omitted */ }

A wrapper object providing device restore routines to a context.

Methods

impl DeviceRestore

pub fn from_raw_weak(context: *mut ContextInternal) -> Self

Create a new DeviceManager from an existing ContextInternal pointer. This is the 'weak' version, for use in callbacks, which avoids destroying the internal object when dropped.

pub fn test(&mut self, cb: (TestCb, *mut c_void)) -> Option<Operation>

Test if this extension module is available in the server.

pub fn subscribe(
    &mut self,
    enable: bool,
    cb: (ContextSuccessCb, *mut c_void)
) -> Option<Operation>

Subscribe to changes in the device database.

pub fn set_subscribe_cb(&mut self, cb: (SubscribeCb, *mut c_void))

Set the subscription callback that is called when subscribe was called.

pub fn read_formats_all(
    &mut self,
    cb: (ReadDevFormatsCb, *mut c_void)
) -> Option<Operation>

Read the formats for all present devices from the device database.

pub fn read_formats(
    &mut self,
    type_: Device,
    idx: u32,
    cb: (ReadDevFormatsCb, *mut c_void)
) -> Option<Operation>

Read an entry from the device database.

pub fn save_formats(
    &mut self,
    type_: Device,
    idx: u32,
    formats: &mut [&mut Info],
    cb: (ContextSuccessCb, *mut c_void)
) -> Option<Operation>

Read an entry from the device database.
