clippy complains about error: variables can be used directly in the `format!` string. caused by the update(ci, step Run dtolnay/rust-toolchain@master):

stable-x86_64-unknown-linux-gnu updated - rustc 1.88.0 (6b00bc388 2025-06-23) (from rustc 1.87.0 (17067e9ac 2025-05-09))

should we ignore(allow) it? or I can fix them in another pr (almost all crates are involved).

however, I have already fixed warnings in this crate(w). :P

I'll fix it later
