TBF, that's not a fair comparison. The Rust example omits a bunch of code (the ... parts) for the different cases.
As someone who likes Rust, I think this is a pretty poor problem to show off Rust. You can make the C version look very similar.
They extracted the fromhex function from the Rust code into it's own function but left it in the C code to look ugly. That I think is unfair
The issue isn't the length of the code, it's the handling of failure cases
Yes, that's the major win for Rust here... but that isn't at all obvious from just seeing the slides.
