#[repr(C)]
pub struct Arg(_);
Expand description
Contains an untyped pointer to a function argument.
When calling a function via a CIF, each argument
must be passed as a C void*
. Wrapping the argument in the Arg
struct accomplishes the necessary coercion.
pub fn new<T>(r: &T) -> Self
Coerces an argument reference into the Arg
type.
This is used to wrap each argument pointer before passing them
to Cif::call
.
