Thanks! Just a couple nitpicks below.

The return type in the C header is void* but here we have *mut u8. For consistency, either

this should change to *mut std::ffi::c_void

or the C header should change to uint8_t*

Can you document in the C header's docs for the wasmtime_memory_creator_t that the functions need to be thread safe? Thanks.

One suggestion I'd have for this is to have a void* that's passed into new_memory as well, but then that would make it a bit confusing since a different void* is passed to new vs get/grow. In that case I might additionally recommend one of two changes:

Split this structure into "creator callbacks" with new + finalizer and "memory callbacks" with get + grow + finalizer

Move the new_memory callback to the wasmtime_config_host_memory_creator_set function as an argument.

I'm somewhat partial to (1) here, but could go either way (I don't design that many C APIs)
