The following code does not parse.

I tried this code:

pub struct Test {
    #[cfg(not(any(
        target_os = "solaris",
        target_os = "illumos",
        target_os = "fuchsia",
        target_os = "redox",
    )))]
    _value: bool,
}

pub fn test() -> Test {
    Test {
        #[cfg(not(any(
            target_os = "solaris",
            target_os = "illumos",
            target_os = "fuchsia",
            target_os = "redox",
        )))]
        _value: false,
    }
}

I expected to see this happen: Compiles.

Instead, this happened: Compiler parsing error

<source>:13:9: error: unrecognised token '#' in struct (or enum) expression - expected '}', identifier, integer literal, or '..'
   13 |         #[cfg(not(any(
      |         ^
