Struct Gid 

pub struct Gid(pub u16);

A glyph index into a font program.

Zero is a legitimate value — it is the .notdef glyph, which PDFium deliberately distinguishes from “no glyph at all” (that is None, the C++’s -1). Every ladder in this crate returns Option<Gid> for exactly that reason.

Whose numbering this is depends on the loaded program: skrifa’s GlyphId for an sfnt or bare-CFF face, and /CharStrings declaration order for a Type 1 one. pdfrum_type1::Gid names that second space in its own crate and stays a separate type; the From impls below are the conversion, and they live here because this is the one crate that holds both index spaces.
