CurrentThreadTaskCallbackLease

Struct CurrentThreadTaskCallbackLease 

Source
pub struct CurrentThreadTaskCallbackLease { /* private fields */ }
Expand description

Retains one admitted CurrentThread host callback in its runtime generation.

The host must keep this opaque lease alive until its native callback has acknowledged or failed the delivery and destroyed every callback-owned payload. The Rc marker prevents moving a TLS generation guard to another thread before it restores the callback thread’s prior runtime identity.
