Emit `PhantomData<UnsafeCell<T>>` members for all generic parameters This makes generated generic structs lifetime invariant, since we cannot know the C++ type's true variance. Fixes #506 Rebased + squashed version of #635; cc @Kowasaki To resolve the conflicts and rebase and squash, I did essentially these commands: ``` $ git fetch servo $ git checkout -b Kowasaki-master servo/master $ git merge --squash --edit Kowasaki/master $ cargo test $ cd tests/expectations $ cargo test $ cd - $ git commit --author="Kowasaki" $ git push fitzgen Kowasaki-master ``` Hopefully that is useful for you in the future :) Thanks for fixing this issue!
bindgen
bindgen automatically generates Rust FFI bindings to C and C++ libraries.
For example, given the C header cool.h:
typedef struct CoolStruct {
int x;
int y;
} CoolStruct;
void cool_function(int i, char c, CoolStruct* cs);
bindgen produces Rust FFI code allowing you to call into the cool library's
functions and use its types:
/* automatically generated by rust-bindgen */
#[repr(C)]
pub struct CoolStruct {
pub x: ::std::os::raw::c_int,
pub y: ::std::os::raw::c_int,
}
extern "C" {
pub fn cool_function(i: ::std::os::raw::c_int,
c: ::std::os::raw::c_char,
cs: *mut CoolStruct);
}
