Subject: [PATCH v2 22/28] rust: str: add `fmt!` macro
Date: Fri, 2 Dec 2022 17:14:53 +0100 [thread overview]
Message-ID: <20221202161502.385525-23-ojeda@kernel.org> (raw)
In-Reply-To: <20221202161502.385525-1-ojeda@kernel.org>
From: Wedson Almeida Filho <wedsonaf@gmail.com>
Add the `fmt!` macro, which is a convenience alias for the Rust
`core::format_args!` macro.
For instance, it may be used to create a `CString`:
CString::try_from_fmt(fmt!("{}{}", "abc", 42))?
