Subject: [PATCH v3 15/35] completion.h: move declarations to completion_types.h
Date: Sun, 11 Feb 2024 13:29:40 +0100
Message-Id: <20240211123000.3359365-16-max.kellermann@ionos.com>
In-Reply-To: <20240211123000.3359365-1-max.kellermann@ionos.com>

Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

By providing declarations in a lean header, we can reduce header
dependencies.
