When I try to compile this on aarch64, I get the following error:

I believe this is due to arm defining char as unsigned: @https://github.com/ARM-software/abi-aa/blob/main/aapcs64/aapcs64.rst#10arm-c-and-c-language-mappings

how would you fix this while retaining support for all the existing architectures/targets?



and like magic, it fixed it perfectly without me needing to spend a couple hours reading Rust 101
