Struct FontRegistry 

pub struct FontRegistry { /* private fields */ }

Registry of loaded fonts keyed by font stack names.

A “font stack” is a comma-separated list of font family names (e.g. "Noto Sans Regular, Arial Unicode MS Bold"). The registry resolves the first available font for each stack.
