Subject: Re: [PATCH] rust: Enable the new_uninit feature for kernel and driver crates
Date: Wed, 01 Mar 2023 18:24:26 +0100 [thread overview]
Message-ID: <CQV7ZNT6LMXI.1XG4YXSH8I7JK@vincent-arch> (raw)
In-Reply-To: <20230224-rust-new_uninit-v1-1-c951443d9e26@asahilina.net>
> The unstable new_uninit feature enables various library APIs to create
> uninitialized containers, such as `Box::assume_init()`. This is
> necessary to build abstractions that directly initialize memory at the
> target location, instead of doing copies through the stack.
>
> Will be used by the DRM scheduler abstraction in the kernel crate, and
> by field-wise initialization (e.g. using `place!()` or a future
> replacement macro which may itself live in `kernel`) in driver crates.

> See [1] [2] [3] for background information.
