Subject: [pdm-devel] [PATCH proxmox v2 4/5] docgen: add docgen crate
Date: Thu, 13 Nov 2025 13:00:16 +0100 [thread overview]
Message-ID: <20251113120021.331639-5-s.sterz@proxmox.com> (raw)
In-Reply-To: <20251113120021.331639-1-s.sterz@proxmox.com>
currently this is limited to dumping a `Router` into a `Value` which
can be serialized to JSON and interpreted by an api viewer.
