Subject: [pve-devel] [PATCH proxmox-firewall 07/15] use std::mem::take over drain()
Date: Wed, 11 Sep 2024 11:31:08 +0200	[thread overview]
Message-ID: <20240911093116.112960-8-s.hanreich@proxmox.com> (raw)
In-Reply-To: <20240911093116.112960-1-s.hanreich@proxmox.com>

This is more efficient than draining and collecting the Vec. It also
fixes the respective clippy lint.
