bindgen test.h --generate types,methods,functions,vars -- -x c++

Actual Results

/* automatically generated by rust-bindgen */

#[repr(C)]
#[derive(Debug, Copy)]
pub struct Foo {

#[test]
fn bindgen_test_layout_Foo() {

}
impl Clone for Foo {
    fn clone(&self) -> Self { *self }
}

Expected Results

I should get the output from bindgen test.h -- -x c++, which includes the constructor:

/* automatically generated by rust-bindgen */

This assumes that Foo is movable by byte-level copying. If it had internal pointers to itself, this would likely break. Without some Rust-level mechanism to call a method on moves, it's not going to be safe to directly embed C++ types in a Rust type. The C++ type either has to be Boxed or a C++ new allocation.

gsingh93 · 2017-03-30T18:53:34Z

ping @emilio. Any thoughts on this?

I assumed that rust would do RVO and avoid the move itself, but yeah, it'd be safer to just provide a construct function that took a &mut V or something like that.

I'm looking into the code generation issue. Thanks for the ping, this got lost in a pile of other email :(

emilio · 2017-04-03T10:53:33Z

Sorry for the lag here, got sidetracked. #606 allows configuring this from the command line, filled #607 for the memmovable requirement for constructors.

options: Allow configuring the generation of constructors. Fixes #556 Sorry for the delay fixing this btw.
