#![allow(unused, nonstandard_style)]

// If an enum has two different variants,
// then it cannot be matched upon in a function argument.
// It still gets an error, but no suggestions.
enum Foo {
    C,
    D,
}

fn foo(C: Foo) {} //~ERROR

fn main() {
    let C = Foo::D; //~ERROR
}
fix(lint): don't suggest refutable patterns to "fix" irrefutable bind In function arguments and let bindings, do not suggest changing `C` to `Foo::C` unless `C` is the only variant of `Foo`, because it won't work. The general warning is still kept, because code like this is confusing. Fixes #88730 2021-09-28 00:16:04 +00:00			`#![allow(unused, nonstandard_style)]`
