Struct libpulse_binding::context::ext_device_restore::DeviceRestore

pub struct DeviceRestore {
    pub context: *mut ContextInternal,
    // some fields omitted
}

A wrapper object providing device restore routines to a context.

Fields

context: *mut ContextInternal

Methods

impl DeviceRestore

fn from_raw(context: *mut ContextInternal) -> Self

Create a new DeviceManager from an existing ContextInternal pointer.

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.

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

Test if this extension module is available in the server.

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

Subscribe to changes in the device database.

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

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

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

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

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

Read an entry from the device database.

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

Read an entry from the device database.
