How does this compare to Corrode? The trouble with these things is that the Rust that comes out is usually too awful to maintain. Corrode, too, said that someday they'd generate more reasonable Rust. But that never happened. Converting C into Rust with unsafe raw pointers is not all that useful.
What's needed is some way to provide key information C doesn't have. Mostly about array sizes. Some way to annotate
int read(int fd, void* buf, size_t len)
to tell the system that buf has size len.
A file of translation hints with such info could guide the translator into producing decent Rust. Most of the things done with pointer arithmetic can be expressed with slices. (Things being done with pointer arithmetic which can't be expressed as slices should be viewed with deep suspicion.) But you need size info to do that.
