Detailed Description

RAII slot guard for ConcurrencyLimiter — acquires on construction, releases on destruction.

The constructor calls ConcurrencyLimiter::acquireSlot on limiter (which may block); the destructor calls ConcurrencyLimiter::releaseSlot. Passing nullptr makes both operations no-ops, so guard sites that may or may not be limited can be written without branching. Not copyable nor movable.
