pub fn install_panic_hook()Expand description
Install a panic hook that records the panic through log::error! before the
default hook runs.
§Why it chains rather than replaces
utils::lock installs a silencing hook around its own tests, which
deliberately provoke poisoned locks. Replacing the current hook here would
make that test output scream about panics it is intentionally causing — and,
more importantly, replacing whatever hook is present is how you lose the
backtrace the runtime would otherwise print.
