Another example fn pass_to_ptr_call<T>(f: fn(T), x: T) {
f(x);
}
trait TrackedTrait {
fn trait_tracked_unit_default(_: ()) {
let location = std::panic::Location::caller();
assert_eq!(location.file(), file!());
}
}
impl TrackedTrait for () {}
fn main() {
pass_to_ptr_call(<() as TrackedTrait>::trait_tracked_unit_default, ());
} |
Similar case but additional Codepub struct S();
pub trait X {
fn unused3(var: i32) {
println!("{}", var);
}
}
impl X for S {}
fn main() {} Command
