[−][src]Struct libpulse_glib_binding::Mainloop
This acts as a safe interface to the internal PA Mainloop.
The mainloop object pointers are further enclosed here in a ref counted wrapper, allowing this outer wrapper to have clean methods for creating event objects, which can cleanly pass a copy of the inner ref counted mainloop object to them. Giving this to events serves two purposes, firstly because they need the API pointer, secondly, it ensures that event objects do not outlive the mainloop object.
Fields
_inner: Rc<MainloopInner<MainloopInternal>>
The ref-counted inner data.
Methods
impl Mainloop
[src]
pub fn new(context: Option<&mut GMainContext>) -> Option<Self>
[src]
Creates a new GLIB main loop object for the specified GLIB main loop context.
Takes an argument context
for the GMainContext
to use. If context is None
the default
context is used.
This returns the object in an Rc wrapper, allowing multiple references to be held, which allows event objects to hold one, thus ensuring they do not outlive it.
pub fn get_api<'a>(&self) -> &'a MainloopApi
[src]
Gets the abstract main loop abstraction layer vtable for this main loop.
No need to free the API as it is owned by the loop and is destroyed when the loop is freed.
Talking to PA directly with C requires fetching this pointer explicitly via this function. This is actually unnecessary through this binding. The pointer is retrieved automatically upon Mainloop creation, stored internally, and automatically obtained from it by functions that need it.
