Struct Word 

pub(crate) struct Word {
    pub(crate) text: String,
    pub(crate) actual_text: Option<String>,
    pub(crate) font: Font,
    pub(crate) size_pt: f32,
    pub(crate) width_pt: f32,
    pub(crate) subruns: Vec<WordSubRun>,
    pub(crate) shy_break_offsets: Vec<usize>,
}

Fields

text: String

actual_text: Option<String>

font: Font

Primary face – the style-resolved choice from the active FontFamily (regular/bold/italic/monospace). Used for line metrics (ascent/descent), inter-word spacing, and character-wise hyphenation width estimates. Per-glyph fallback faces (e.g. Noto Sans Math for <=) live inside Word::subruns.

size_pt: f32

width_pt: f32

Pre-computed advance width – populated when the word is constructed in collect_words (sum of subruns[i].advance_pt) so the line-breaker doesn’t re-measure on every comparison.

subruns: Vec<WordSubRun>

Per-glyph-fallback sub-runs produced by shape_with_fallback. One sub-run per contiguous source span that shares a face; each carries its own font + text slice + glyph stream with cluster offsets rebased to its local text. flush_line emits one crate::TextRun per sub-run, advancing the x cursor by subrun.advance_pt between them. For Base14 primary faces the result is always a single sub-run with empty glyphs (no fallback target – Base14 emit path uses WinAnsi-byte strings instead).

shy_break_offsets: Vec<usize>

Byte offsets into text where the source contained a U+00AD soft hyphen. The SHY codepoints are stripped before shaping (split_soft_hyphens in the layout crate); these offsets mark the cluster boundaries where the author permits a line break. The greedy breaker consults them via try_shy_break when a word would otherwise overflow the line: the chosen prefix gets a visible - appended and the suffix continues as the next word. The Knuth-Plass cutover will use the same offsets as flagged Penalty(50) items for optimal (non-greedy) selection.
