Struct HandleOwner

source 
pub struct HandleOwner<D: Send + Sync>(/* private fields */);
Expand description

A Handle owner.

Use Handle::new to create.

Dropping the HandleOwner marks all active handles as force-drop.

Implementations§

source§

impl<D: Send + Sync> HandleOwner<D>

source

pub fn is_dropped(&self) -> bool

If the handle is in dropped state.

The handle is considered dropped when all handle and clones are dropped or when force_drop was called in any of the clones.

source

pub fn weak_handle(&self) -> WeakHandle<D>

Gets an weak handle that may-not be able to upgrade.

source

pub fn data(&self) -> &D

Reference the attached data.
