[−][src]Struct abi_stable::std_types::arc::RArc
Ffi-safe version of ::std::sync::Arc<_>
Methods
impl<T> RArc<T>
[src]
impl<T> RArc<T>
[src]
pub fn into_arc(this: Self) -> Arc<T> where
T: Clone,
[src]
T: Clone,
Converts this into an Arc<T>
Allocators
The reason RArc<T>
cannot always be converted to an Arc<T>
is
because their allocators might be different.
When is T cloned
T
is cloned if the current dynamic_library/executable is
not the one that created the RArc<T>
,
and the strong count is greater than 1.
pub fn try_unwrap(this: Self) -> Result<T, Self>
[src]
Attempts to unwrap this RArc<T>
into a T
,
returns Err(self) if the RArc<T>
s strong count is greater than 1.
pub fn get_mut(this: &mut Self) -> Option<&mut T>
[src]
Attempts to create a mutable reference to T
,
failing if RArc<T>
s strong count is greater than 1.
pub fn make_mut<'a>(this: &'a mut Self) -> &'a mut T where
T: Clone,
[src]
T: Clone,
Makes a mutable reference to T
,
if there are other RArc<T>
s pointing to the same value,
then T
is cloned to ensure unique ownership of the value.
Postconditions
After this call, the strong count of this
will be 1,
because either it was 1 before the call,
or because a new RArc<T>
was created to ensure unique ownership of T
.
