How would I port Arduino C++ libraries to Rust Embedded (i.e. rp-hal)

Does anyone have any way I could port an Arduino C++ library like the Adafruit LIS3DH or Adafruit SSD1306 libraries to Rust Embedded especially for the RP2040?

I've got lots of external devices that I see aren't supported (yet!) by a library on the Rust Driver Crates. I suppose for smaller sensors like my LIS3DH, I'm confident enough in Rust embedded to write a library (though I'm not sure how, any pointers would be appreciated) but I'm completely gone at rewriting something resembling Adafruits SSD1306. Thanks!

Rather than needlessly translating all that working code from C++ to Rust (and then needing to extensively test and debug it), it would be more productive, and less error prone Probably easier, safer, more productive to wrap it in a Rust interop layer. C/Rust interop is well defined, and can be adapted for use with C++ (by utilising C/C++ interop) as an intermediate. Described in the Embedded Rust documentation: https://docs.rust-embedded.org/book/interoperability/c-with-rust.html.
