Struct Span 

pub struct Span {
    pub range: (usize, usize),
    pub color: Option<Color>,
    pub weight: Option<FontWeight>,
}

One styled range of the document — a token from the app’s own tokenizer (a markdown bold run, a JSON string, a syntax-highlighted keyword). None fields fall back to the widget’s own default text color/weight, so a SpanSource only needs to describe what it wants to OVERRIDE, not restate the whole style for every char.

Fields

range: (usize, usize)

color: Option<Color>

weight: Option<FontWeight>
