Feature
Implement Linker::func_wrap() functionality to the C/C++ APIs to be able to instantiate all hostcall functions once within an application with short lived Stores.
Benefit
Brings C/C++ APIs in alignment with Rust API, and would provided a significant performance benefit for applications with short lived Stores. For example, server applications which provide hostcalls to access request data. In my use case, I am using the C++ API and notice a large performance hit when registering even a single hostcall (via Linker::define()).
Implementation
I'm not sure what would be required to expose this functionality in the C/C++ API.
Alternatives
The main goal I would like to achieve would be to register all hostcalls once up front to avoid the overhead of registering all hostcalls for each Store context.
Thank you!
