placement_new_protocol
#27779)Owner
is the type of the end value of in (PLACE) EXPR
Note that when in (PLACE) EXPR
is solely used for
side-effecting an existing data-structure,
e.g. Vec::emplace_back
, then Owner
need not carry any
information at all (e.g. it can be the unit type ()
in that
case).
Required Methods
unsafe fn finalize(self) -> Self::Owner
Unstable (
placement_new_protocol
#27779)Converts self into the final value, shifting
deallocation/cleanup responsibilities (if any remain), over to
the returned instance of Owner
and forgetting self.
