Error: mismatched types on 32 bit architectures

When trying to build this on 32-bit system I get this error:

error[E0308]: mismatched types

help: you can convert a `u64` to a `u32` and panic if the converted value doesn't fit

Full build log here: https://buildd.debian.org/status/fetch.php?pkg=rust-udevrs&arch=armel&ver=0.3.0-2&stamp=1731531071&raw=0

The error seems to be present on at least armel, armhf and i386 but it looks to be to be a generic 32-vs-64 bit problem.
