Table

A simple trait used for accessing table-like objects.

This trait is used internally for the machine's constant table. As long as your table type implements this trait then you'll be cool. Meaning you can choose whatever language semantics you want with regards constants.

Associated Types

type Item

The type for items stored and retrieved from the table.
