pub struct WithParachute<'scope, T> { /* private fields */ }
Expand description
Data that has been protected with a parachute.
When a parachute is attached to data with AttachParachute::attach_parachute
, ownership of
the data is transfered from Rust to Julia. This ensures the data will be dropped safely, even
if Julia throws an exception and would have jumped over the pending drop without a parachute.
Unlike other managed types, WithParachute
doesn’t implement Managed
but behaves like a
mutable reference to the protected data: it implements Deref
and DerefMut
to allow using
protected data as if it were a mutable reference to the original data. The parachute can be
removed by calling WithParachute::remove_parachute
to regain ownership.
For more information, see the module-level docs.
