UnboundObjectPoolRef

Struct UnboundObjectPoolRef 

Source
pub struct UnboundObjectPoolRef<T: Send> { /* private fields */ }
Expand description

One item borrowed from an UnboundObjectPoolDeref/DerefMut to T for normal use, and returns itself to the pool (after running release on it) when dropped.

Meant to be wrapped in an Arc wherever it needs to be shared/cloned downstream (see crate::buffer::MediaBuffer::Video) — cloning the Arc is what lets e.g. crate::elements::Tee fan the same frame out to multiple branches cheaply, and the item only actually goes back to the pool once every one of those clones has been dropped. This type itself is deliberately not Clone: only one thing can hold the actual boxed value at a time, or “return it once the last reference drops” wouldn’t mean anything.
