Static rustc_lint::builtin::FUNCTION_ITEM_REFERENCES
source · pub static FUNCTION_ITEM_REFERENCES: &'static Lint
Expand description
The function_item_references
lint detects function references that are
formatted with fmt::Pointer
or transmuted.
Example
fn foo() { }
fn main() {
println!("{:p}", &foo);
}
{{produces}}
Explanation
Taking a reference to a function may be mistaken as a way to obtain a
pointer to that function. This can give unexpected results when
formatting the reference as a pointer or transmuting it. This lint is
issued when function references are formatted as pointers, passed as
arguments bound by fmt::Pointer
or transmuted.
