Struct ffi_cif 

Source 
#[repr(C)]
pub struct ffi_cif {
    pub abi: ffi_abi,
    pub nargs: c_uint,
    pub arg_types: *mut *mut ffi_type,
    pub rtype: *mut ffi_type,
    pub bytes: c_uint,
    pub flags: c_uint,
}
Expand description

A struct used by libffi to describe a function’s ABI and type signature.

It is recommended to not fill out the fields in a ffi_cif manually, but rather supply the correct arguments to ffi_prep_cif.
