Struct libpulse_binding::context::ext_stream_restore::StreamRestore

pub struct StreamRestore { /* private fields */ }

A wrapper object providing stream restore routines to a context. Note: Saves a copy of active multi-use closure callbacks, which it frees on drop.

Implementations

impl StreamRestore

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

Test if this extension module is available in the server.

Panics if the underlying C function returns a null pointer.

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

Read all entries from the stream database.

Panics if the underlying C function returns a null pointer.

pub fn write<F>(
    &mut self,
    mode: UpdateMode,
    data: &[&Info<'_>],
    apply_immediately: bool,
    callback: F
) -> Operation<dyn FnMut(bool)>where
    F: FnMut(bool) + 'static,

Store entries in the stream database.

The callback must accept a bool, which indicates success.

Panics if the underlying C function returns a null pointer.

pub fn delete<F>(
    &mut self,
    streams: &[&str],
    callback: F
) -> Operation<dyn FnMut(bool)>where
    F: FnMut(bool) + 'static,

Delete entries from the stream database.

The callback must accept a bool, which indicates success.

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,

Subscribe to changes in the stream 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() + 'static,

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

Trait Implementations

impl Drop for StreamRestore

fn drop(&mut self)
