Struct libpulse_binding::context::ext_device_restore::DeviceRestore

pub struct DeviceRestore { /* fields omitted */ }

A wrapper object providing device restore routines to a context.

Note: Saves a copy of active multi-use closure callbacks, which it frees on drop.

Methods

impl DeviceRestore

pub fn test<F>(&mut self, callback: F) -> Operation<dyn FnMut(u32)> where
    F: FnMut(u32) + 'static, 

Tests if this extension module is available in the server.

The callback must accept an integer, which indicates version.

Panics if the underlying C function returns a null pointer.

pub fn subscribe<F>(
    &mut self,
    enable: bool,
    callback: F
) -> Operation<dyn FnMut(bool)> where
    F: FnMut(bool) + 'static, 

Subscribes to changes in the device database.

The callback must accept a bool, which indicates success.

Panics if the underlying C function returns a null pointer.

pub fn set_subscribe_cb<F>(&mut self, callback: F) where
    F: FnMut(Device, u32) + 'static, 

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

The callback must accept two parameters, firstly a ::def::Device variant, and secondly an integer index.

pub fn read_formats_all<F>(
    &mut self,
    callback: F
) -> Operation<dyn FnMut(ListResult<&Info>)> where
    F: FnMut(ListResult<&Info>) + 'static, 

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

Panics if the underlying C function returns a null pointer.

pub fn read_formats<F>(
    &mut self,
    type_: Device,
    index: u32,
    callback: F
) -> Operation<dyn FnMut(ListResult<&Info>)> where
    F: FnMut(ListResult<&Info>) + 'static, 

Reads an entry from the device database.

Panics if the underlying C function returns a null pointer.

pub fn save_formats<F>(
    &mut self,
    type_: Device,
    index: u32,
    formats: &mut [&mut Info],
    callback: F
) -> Operation<dyn FnMut(bool)> where
    F: FnMut(bool) + 'static, 

Reads an entry from the device database.

The callback must accept a bool, which indicates success.

Panics if the underlying C function returns a null pointer.
