Module traversal

Experimental generic traversal of font tables.

This module defines functionality that allows untyped access to font table data. This is used as the basis for things like debug printing.

The basis of traversal is the SomeTable trait, which is implemented for all font tables. This trait provides the table’s name, as well as ordered access to the table’s fields. Using this, it is possible to iterate through a table and its subtables, records, and values.

Warning

This functionality is considered experimental, and the API may break or be removed without warning.
