Subject: [PATCH v3 06/15] rust/vmstate: Fix "cannot infer type" error in vmstate_struct
Date: Tue, 18 Mar 2025 21:02:10 +0800	[thread overview]
Message-ID: <20250318130219.1799170-7-zhao1.liu@intel.com> (raw)
In-Reply-To: <20250318130219.1799170-1-zhao1.liu@intel.com>

Rust cannot infer the type (it should be VMStateField) after
Zeroable::ZERO, which cause the compiling error.

To fix this error, call with_varray_flag() after VMStateField's
initialization.
