E0606 `"hello" as bool` could suggest `is_empty()`

[matthiaskrgr]

Code

fn main() {
    let v = "hello" as bool;
}

Current output

error[E0606]: casting `&'static str` as `bool` is invalid
 --> src/lib.rs:2:13
  |
2 |     let v = "hello" as bool;
  |             ^^^^^^^^^^^^^^^

For more information about this error, try `rustc --explain E0606`.

Desired output

error[E0606]: casting `&'static str` as `bool` is invalid
 --> src/lib.rs:2:13
  |
2 |     let v = "hello" as bool;
  |             ^^^^^^^^^^^^^^^

help: to find out if a &str or String contains something or not, use: `!"hello".is_empty()`
