Subject: [PATCH RFC 2/4] rust: prelude: re-export `zerocopy::Immutable`
Date: Sun, 28 Jun 2026 17:10:15 +0000 [thread overview]
Message-ID: <20260628-dma-zerocopy-bridge-v1-2-9a2895ebe30d@gmail.com> (raw)
In-Reply-To: <20260628-dma-zerocopy-bridge-v1-0-9a2895ebe30d@gmail.com>
From: SeungJong Ha <engineer.jjhama@gmail.com>
`impl_transmute_via_zerocopy!` requires `Immutable` (no interior
mutability) alongside `FromBytes`/`IntoBytes`. Re-export it from the
prelude like the other two.
