pub(crate) struct Features(());
Expand description
A witness indicating that CPU features have been detected and cached.
TODO: Eventually all feature detection logic should be done through
functions that accept a Features
parameter, to guarantee that nothing
tries to read the cached values before they are written.
This is a zero-sized type so that it can be “stored” wherever convenient.
