Subject: rust: prelude: re-export `core::mem::{align,size}_of{,_val}`
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=72b04a8af7fb11e0f12e52985543d7e699fd4406;p=users%2Fhch%2Fmisc.git

rust: prelude: re-export `core::mem::{align,size}_of{,_val}`

Rust 1.80.0 added:

    align_of
    align_of_val
    size_of
    size_of_val

from `core::mem` to the prelude [1].

For similar reasons, and to minimize potential confusion when code may
work in later versions but not in our current minimum, add it to our
prelude too.
