Struct GPtr

Source
pub struct GPtr<T: RefCounted> { /* private fields */ }
Expand description

Similar to Arc, but does not call release while the reference count is greater than or equal to zero.

It differs from Arc in that it does not have its own reference-counting field. In other words, it manipulates the pointer it holds via an external reference count and drop implementation.
