Update bindgen 0.63.0 -> 0.71.1 (#116)

[beuss-git]

bindgen 0.63.0 didn't expand/include the following macros on some systems:

// {ROS_BASE}/include/rosidl_runtime_c/rosidl_runtime_c/primitives_sequence_functions.h
...
ROSIDL_RUNTIME_C__DECLARE_PRIMITIVE_SEQUENCE_FUNCTIONS(float)
ROSIDL_RUNTIME_C__DECLARE_PRIMITIVE_SEQUENCE_FUNCTIONS(double)
ROSIDL_RUNTIME_C__DECLARE_PRIMITIVE_SEQUENCE_FUNCTIONS(long_double)
...

This change fixes this by now generating the missing primitive sequence functions.
I have manually tested it to compile and work on Ubuntu 22.04 with ROS2 Humble and Iron using some simple messages.

Cool. Which rust version do you use? When I'm trying this with 1.85.0, I'm getting this error: rust-lang/rust-bindgen#3149. When I downgrade bindgen to 0.70.0, as suggested in that issue, it works.

[beuss-git]

Hmm, that's a bit unfortunate.
I am pretty close in version to you.

$ rustc --version
rustc 1.85.1 (4eb161250 2025-03-15)

I found the source of my problem. I had to update proc-macro2 by running cargo update proc-macro2 --precise 1.0.80. See rust-lang/rust-bindgen#3149 (comment).

Hello. Thanks! I will merge this shortly. But then we should update again once bindgen releases a new version I guess.

I've been seeing the same issue today using rust 1.85.1, upgrading to this branch fixed my issue. Thank you.
