From: brian m. carlson Date: Mon, 27 Oct 2025 00:43:54 GMT Subject: [PATCH 04/14] rust: add a ObjectID struct Message-ID: <20251027004404.2152927-5-sandals@crustytoothpaste.net> In-Reply-To: <20251027004404.2152927-1-sandals@crustytoothpaste.net> We'd like to be able to write some Rust code that can work with object IDs. Add a structure here that's identical to struct object_id in C.
