However, CR0.WP is enabled at boot, and generally remains set for the life of a system. In this case, a page fault will be triggered in response to the write. As more of a tool to facilitate Copy-on-Write than a security boundary, this does not present any real restriction upon the kernel. That said, it does require the inconvenience of fault handling, which would not otherwise be necessary.
Bindgen restricts which types can be passed across the boundary. The one folks often run into first is that &[T] only works when T is IntoWasmAbi (including JS-imported types4) — i.e. usually not your Rust-exported structs. This means that you are often forced to construct a Vec. This makes sense since JS is going to take control over the resulting JS array, and can mutate it as it pleases. It also means that when the type comes back in, you are unable to accept it as &[T] or Vec unless the earlier IntoWasmAbi caveat applies.
