= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #56105 <https://github.com/rust-lang/rust/issues/56105>
= note: this behavior recently changed as a result of a bug fix; see rust-lang/rust#56105 for details
note: the lint level is defined here
