Struct ExtentsSources 

struct ExtentsSources<'a> {
    items: [Option<ExtentsSource<'a>>; 6],
    len: usize,
}

The sources available in a font, in the order they are tried.

The three bitmap tables, COLR and VARC take an entry each, and the four outline sources share one, so six entries always suffice.

Fields

items: [Option<ExtentsSource<'a>>; 6]

len: usize
