-// check-pass
-//! Unless visibility is assumed, a transmutation should be rejected if the
-//! destination type contains an unreachable field (e.g., a public field with a
-//! private type). (This rule is distinct from type privacy, which still may
-//! forbid naming such types.)
-//!
-//! This test exercises a tricky-to-implement instance of this principle: the
-//! "pub-in-priv trick". In the below example, the type `dst::private::Zst` is
-//! unreachable from `Context`.
