Struct Unsafe
sealed struct Unsafe
Require native code.
When this attribute is attached to an interface or method, the
thing to which this attribute is attached can be called only from
“unsafe” contexts, which usually means C++ or unsafe Rust.
We use this attribute to define “magical” interfaces that don’t
obey the usual rules of the type system. The IDL compiler lets you
use this interface only in APMF packages.
