Subject: [PATCH v3 2/6] rust: list: use consistent type parameter style
Date: Wed, 23 Apr 2025 12:30:03 -0400	[thread overview]
Message-ID: <20250423-list-no-offset-v3-2-9d0c2b89340e@gmail.com> (raw)
In-Reply-To: <20250423-list-no-offset-v3-0-9d0c2b89340e@gmail.com>

Refer to the type parameters of `impl_has_list_links{,_self_ptr}!` by
the same name used in `impl_list_item!`. Capture type parameters of
`impl_list_item!` as `tt` using `{}` to match the style of all other
macros that work with generics.
