Static IMPROPER_CTYPES

static IMPROPER_CTYPES: &Lint

The improper_ctypes lint detects incorrect use of types in foreign modules.

Example

extern "C" {
    static STATIC: String;
}

{{produces}}

Explanation

The compiler has several checks to verify that types used in extern blocks are safe and follow certain rules to ensure proper compatibility with the foreign interfaces. This lint is issued when it detects a probable mistake in a definition. The lint usually should provide a description of the issue, along with possibly a hint on how to resolve it.
