Use parenthetical notation for `Fn` traits Always use the `Fn(T) -> R` format when printing closure traits instead of `Fn<(T,), Output = R>`. Address #67100: ``` error[E0277]: expected a `Fn()` closure, found `F` --> file.rs:6:13 | 6 | call_fn(f) | ------- ^ expected an `Fn()` closure, found `F` | | | required by a bound introduced by this call | = note: wrap the `F` in a closure with no arguments: `|| { /* code */ }` note: required by a bound in `call_fn` --> file.rs:1:15 | 1 | fn call_fn<F: Fn() -> ()>(f: &F) { | ^^^^^^^^^^ required by this bound in `call_fn` help: consider further restricting this bound | 5 | fn call_any<F: std::any::Any + Fn()>(f: &F) { | ++++++ ``` |
