tests: Add missing run-pass annotations 2019-07-26 21:54:25 +00:00			`// run-pass`
Move main removal to its own pass in --test mode This handles the case where the #[main] function is buried deeper in the ast than we search for #[test] functions. I'm not sure why one would want to do that, but since it works in standard compilation it should also work for tests. 2015-08-24 15:34:04 +00:00			`// compile-flags: --test`

Make closures and generators a must use types Warn about unused expressions with closure or generator type. This follows existing precedence of must use annotations present on `FnOnce`, `FnMut`, `Fn` traits, which already indirectly apply to closures in some cases, e.g.,: ```rust fn f() -> impl FnOnce() { \|\| {} } fn main() { // an existing warning: unused implementer of `std::ops::FnOnce` that must be used: f(); // a new warning: unused closure that must be used: \|\| {}; } ``` 2020-07-28 00:00:00 +00:00			`(\|\| {`
