[INFO] [stdout]     = note: the temporary is part of an expression at the end of a block;
[INFO] [stdout]             consider forcing this temporary to be dropped sooner, before the block's local variables are dropped
[INFO] [stdout]     = warning: this changes meaning in Rust 2024
[INFO] [stdout]     = note: for more information, see <https://doc.rust-lang.org/edition-guide/rust-2024/temporary-tail-expr-scope.html>
[INFO] [stdout] help: for example, you could save the expression's value in a new local variable `x` and then make `x` be the expression at the end of the block
