pub fn add_to_linker(linker: &mut Linker<HostState>) -> Result<()>Expand description
Register both act:credentials instances in the linker.
Both, not one: store uses types from types, so the elaborated world
imports both instances, and a guest importing act:credentials/store
fails instantiation on an unregistered act:credentials/types@0.1.0. The
interface carries no functions, but the instance must still exist.
