Replace std::ffi::c_uint w/ std::os::raw::c_uint

[mishig25]

Getting error below on Intel CPU Macbook:

cargo check inside safetensors/bindings/python

(base) Mishigs-MacBook-Pro:python mishig$ cargo check
    Checking safetensors-python v0.2.3 (/Users/mishig/Desktop/safetensors/bindings/python)

However, the error goes away when std::ffi::c_uint is replaced with std::os::raw::c_uint

I don't know what's the difference between the two: their docs look identical

which rust version do you have ?

I think I'd rather use ffi than os but I'd prefer to understand why it's missing.

oh you are right:
updated rustc --version from 1.60 to 1.65 & the error is gone !
