Struct compact_rc::rc::RcX

pub struct RcX<T: ?Sized, C>(_)
where
         Cell<C>: RefCount;

Low-memory version of std::rc::Rc.

A type provides almost the same methods as standard Rc. See the top page for about differences from the standard Rc.

There are aliases for simplicity.

• Rc
• Rc8
• Rc16
• Rc32
• Rc64

Implementations

impl<T, C> RcX<T, C>where Cell<C>: RefCount,

pub fn new(value: T) -> RcX<T, C>
