Static rustc_lint::types::IMPROPER_CTYPES_DEFINITIONS
source · [−]static IMPROPER_CTYPES_DEFINITIONS: &'static Lint
Expand description
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.
