// This file documents the entire Host interface API currently used by the WebAssembly script resolver, so the methods
// that can be used from the client wasm.

// we'd like to implement those as well.

// Core functions
// These are the core utility functions for use.
// _error can be used for crash handling in the script handler. It takes a message string, file name string, line and position.
