// The basic stability pattern in this file has four cases:
// 1. no stability attribute at all
// 2. a stable attribute (feature "unit_test")
// 3. an unstable attribute that unit test declares (feature "unstable_declared")
// 4. an unstable attribute that unit test fails to declare (feature "unstable_undeclared")
// 3. an unstable attribute that unit test enables (feature "unstable_declared")
// 4. an unstable attribute that unit test fails to enable (feature "unstable_undeclared")
//
// This file also covers four kinds of visibility: private,
// pub(module), pub(crate), and pub.
