Various utilities

These utilities are not used by MUD itself, they are for developers using MUD.

Functions

systemNamespace

Fetches the namespace of the current system.

This function determines the system's namespace based on its interaction with the store. If the system is a root system, it returns the root namespace (an empty string). Otherwise, it retrieves the namespace using the system's registry. This function must be used within the context of a system (either directly or within libraries called by a system).

function systemNamespace() internal view returns (bytes14);
