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<FnMut(u32)> where     F: FnMut(u32) + 'static,

Test if this extension module is available in the server.

The callback must accept an integer, which indicates version.

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

Subscribe to changes in the device database.

The callback must accept a bool, which indicates success.

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

Set 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<FnMut(ListResult<&Info>)> where     F: FnMut(ListResult<&Info>) + 'static,

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

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

Read an entry from the device database.

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

Read an entry from the device database.

The callback must accept a bool, which indicates success.
