Ruby SDK - Sentry.set_user threadsafe

If I have a Puma server with multiple threads, is Sentry.set_user threadsafe? I just want to make sure I don’t actually send the wrong user information to Sentry if multiple controller requests are being handled at the same time by the same process, but different thread.

EDIT: To clarify I’m talking about the method recommended by Sentry here: Identify Users for Rails | Sentry Documentation
