[−][src]Function artichoke_backend::def::box_unbox_free
pub unsafe extern "C" fn box_unbox_free<T>(
_mrb: *mut mrb_state,
data: *mut c_void
) where
T: 'static + BoxUnboxVmValue,
A generic implementation of a Free
function for
mrb_value
s that store an owned copy of a Box
smart
pointer.
This function ultimately calls Box::from_raw
on the data pointer and
drops the resulting Box
.
Safety
This function assumes that the data pointer is to an Box
<T>
created by
Box::into_raw
. This fuction bounds T
by BoxUnboxVmValue
which
boxes T
for the mruby VM like this.
This function assumes it is called by the mruby VM as a free function for
an MRB_TT_DATA
.
