Subject: [PATCH v3 0/2] Arc methods for linked list
Date: Mon, 11 Mar 2024 16:08:17 +0000 [thread overview]
Message-ID: <20240311-arc-for-list-v3-0-cba1883c62eb@google.com> (raw)
This patchset contains two useful methods for the Arc type. They will be
used in my Rust linked list implementation, which Rust Binder uses. See
the Rust Binder RFC [1] for more information. Both these commits and
the linked list that uses them are present in the branch referenced by
the RFC.
I will send the linked list to the mailing list soon.
