Braden McDorman (Feb 03 2022 at 05:18): Braden McDorman (Feb 03 2022 at 05:18):Hi, I have a Rust function I'm wrapping that needs access to the caller's memory. One of the arguments to the function is a guest pointer (not in the wiggle sense, but a raw u32). Right now I'm storing the Memory in the WasiCtx table to be looked up through the Caller I receive as a parameter. This seems like a hack, though. Is there a better way to go about this? Instantiation order (the instance is exporting the memory) means I can't pass it in through the closure.
