Rust arrays are perfectly compatible with C arrays, they're both just contiguous segments of memory with elements at fixed offsets. You can pass Rust arrays to C functions trivially, and bounds checking has nothing to do with it.

I should also note that all correct C code does bounds checking somewhere. The difference with languages that are bounds-checked by default is that they pessimistically assume that you haven't checked the bound manually, and so can potentially do more bounds checking than is strictly necessary if their optimizers aren't capable of hoisting out the checks.

Ditto for go arrays.
