Struct xpcom::RefPtr

pub struct RefPtr<T: RefCounted + 'static> { /* fields omitted */ }

A smart pointer holding a RefCounted object. The object itself manages its own memory. RefPtr will invoke the addref and release methods at the appropriate times to facilitate the bookkeeping.

Methods

impl<T: RefCounted + 'static> RefPtr<T>

pub fn new(p: &T) -> RefPtr<T>

Construct a new RefPtr from a reference to the refcounted object.

pub unsafe fn from_raw(p: *const T) -> Option<RefPtr<T>>

Construct a RefPtr from a raw pointer, addrefing it.

pub unsafe fn from_raw_dont_addref(p: *const T) -> Option<RefPtr<T>>

Construct a RefPtr from a raw pointer, without addrefing it.

pub unsafe fn forget(self, into: &mut *const T)

Write this RefPtr's value into an outparameter.

Trait Implementations

impl<T: RefCounted + 'static> Deref for RefPtr<T>

type Target = T

fn deref(&self) -> &T

Dereferences the value.

impl<T: RefCounted + 'static> Drop for RefPtr<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: RefCounted + 'static> Clone for RefPtr<T>

fn clone(&self) -> RefPtr<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
