impl<T> AsCtxPtr for T
where T: ?Sized,

Source§

fn as_ctx_ptr(&self) -> *mut Self
where Self: Sized,

self’s address as *mut Self for deferred-task / scopeguard / ref_guard ctx slots. The closures/trampolines deref it as shared (&*p) — every method they reach is &self post-R-2, so no write provenance is required; the *mut spelling is purely to match the existing DerefOnDrop / HasAutoFlush / RefCount ABI.
