Hi Paolo, Thank you for your suggestions, which have been very helpful to us! Currently, we are referring to the Rust implementation of sysbus to develop the Rust version of I2CBus, and we have already made some phased progress. Going forward, we will submit some RFC patches to the upstream for everyone to discuss.
