Subject: [PATCH v8 05/12] rust: use cv! to build Bounded values from constants
Date: Thu, 27 Aug 2026 16:28:33 +0900	[thread overview]
Message-ID: <20260827-chid-v8-5-bc74c77d0214@nvidia.com> (raw)
In-Reply-To: <20260827-chid-v8-0-bc74c77d0214@nvidia.com>

There are some locations which use Bounded::new() which can use the new
cv! macro, so convert them.
