Struct servo_arc::ArcBorrow
[−]
[src]
pub struct ArcBorrow<'a, T: 'a>(_);
A "borrowed Arc". This is a pointer to a T that is known to have been allocated within an Arc.
This is equivalent in guarantees to &Arc<T>, however it is
a bit more flexible. To obtain an &Arc<T> you must have
an Arc
However, Gecko hands us refcounted things as pointers to T directly, so we have to conjure up a temporary Arc on the stack each time. The same happens for when the object is managed by a RawOffsetArc.
ArcBorrow lets us deal with borrows of known-refcounted objects without needing to worry about how they're actually stored.
Methods
impl<'a, T> ArcBorrow<'a, T>[src]
fn clone_arc(&self) -> Arc<T>[src]
unsafe fn from_ref(r: &'a T) -> Self[src]
For constructing from a reference known to be Arc-backed, e.g. if we obtain such a reference over FFI
fn with_arc<F, U>(&self, f: F) -> U where
F: FnOnce(&Arc<T>) -> U,
T: 'static, [src]
F: FnOnce(&Arc<T>) -> U,
T: 'static,
