static IMPROPER_CTYPES_DEFINITIONS: &'static Lint

The improper_ctypes_definitions lint detects incorrect use of extern function definitions.

Example

pub extern "C" fn str_type(p: &str) { }

{{produces}}

Explanation

There are many parameter and return types that may be specified in an extern function that are not compatible with the given ABI. This lint is an alert that these types should not be used. The lint usually should provide a description of the issue, along with possibly a hint on how to resolve it.
