Struct ArcX 

pub struct ArcX<T: ?Sized, C>(/* private fields */)
where
    C: RefCount + Sync + Send;

Low-memory version of std::sync::Arc.

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

There are aliases for simplicity.

• Arc
• Arc8
• Arc16
• Arc32
• Arc64

Implementations

impl<T, C> ArcX<T, C>

where C: RefCount + Sync + Send,

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