Expand `ptr::fn_addr_eq()` documentation. * Describe more clearly what is (not) guaranteed, and de-emphasize the description of rustc implementation details. * Explain what you *can* reliably use it for. Tracking issue for `ptr_fn_addr_eq`: #129322 The motivation for this PR is that I just learned that `ptr::fn_addr_eq()` exists, read the documentation, and thought: “*I* know what this means, but someone not already familiar with how `rustc` works could be left wondering whether this is even good for anything.” Fixing that seems especially important if we’re going to recommend people use it instead of `==` (as per #118833). |
