Struct libpulse_binding::mainloop::api::MainloopInner

pub struct MainloopInner<T> where
    T: MainloopInternalType,  {
    pub ptr: *mut T,
    pub api: *mut MainloopApi,
    pub dropfn: fn(_: &mut MainloopInner<T>),
}

Mainloop inner wrapper.

This contains the actual main loop object pointers, holding both the pointer to the actual opaque main loop C object, and the pointer to the associated API vtable.

An instance of this type will be held, in an Rc ref counted wrapper both in an outer Mainloop wrapper, and by all event objects. With event objects holding a ref-counted copy, this both gives event objects access to the API pointer, which they need, and also it allows us to ensure that event objects do not outlive the main loop object (which internally owns the API object), and thus ensures correct destruction order of event and main loop objects.

Fields

ptr: *mut T

An opaque main loop object

api: *mut MainloopApi

The abstract main loop API vtable for the GLIB main loop object. No need to free this API as it is owned by the loop and is destroyed when the loop is freed.

dropfn: fn(_: &mut MainloopInner<T>)

All implementations must provide a drop method, to be called from an actual drop call.

Trait Implementations

impl<T> Drop for MainloopInner<T> where
    T: MainloopInternalType, 

fn drop(&mut self)

Executes the destructor for this type.

impl<T> MainloopInnerType for MainloopInner<T> where
    T: MainloopInternalType, 

This is the actual implementation of the 'inner type' trait.

It is not possible to replace this with 'default' method implementations within the trait itself since the trait does not know about the existance of the struct attributes being accessed.

type I = T

fn get_ptr(&self) -> *mut T

Return opaque main loop object pointer

fn get_api(&self) -> &mut MainloopApi

Return main loop API object pointer
