Support rust `char` binding, mapping to new cpp `rust::Char` #1147

Open

kraktus wants to merge 1 commit into dtolnay:master from kraktus:rust_char

Proof of concept to support the rust type char which is mapped to rust::Char.

This should be seen as the rust counterpart to #725, and address the other part of #592.

If this is approved, next steps/questions I can think of:

Can we use the rust's char::from_u32 to validate the unicode value? (currently it's a copy of it)
Can cpp's rust::Char be made a POD?
What should be the scope of the API of cpp rust::Char? Currently intentionally minimal
More tests (at least for each supported type in do_typecheck)
