4/// Definitions and functionality to enable guest-to-host function calling,
5/// also called "host functions"
6///
7/// This module includes functionality to do the following
8///
9/// - Define several prototypes for what a host function must look like,
10///   including the number of arguments (arity) they can have, supported argument
11///   types, and supported return types
12/// - Registering host functions to be callable by the guest
13/// - Dynamically dispatching a call from the guest to the appropriate
14///   host function
