[PATCH v2 4/8] reftable/record: constify some parts of the interface

From
Patrick Steinhardt <ps@pks.im>
Date
Dec 28, 2023, 06:27 UTC
Message-ID
<3416268087d474ce45b141105367d7f606bf36a8.1703743174.git.ps@pks.im>
In-Reply-To
<cover.1703743174.git.ps@pks.im>

We're about to convert reftable records to stop storing their object IDs as allocated hashes. Prepare for this refactoring by constifying some parts of the interface that will be impacted by this.
