Struct AddressablePiece 

pub struct AddressablePiece {
    pub start: usize,
    pub end: usize,
    pub content: InlineContent,
    pub format: TextFormat,
}

One piece of a block’s inline content — a text run, an image, or a footnote reference — addressed in the document’s own addressable character space: the space TextDocument::to_addressable_text, find_all match positions, and TextBlock::position all share.

FragmentContent’s offset is deliberately block-relative (0 at the block’s own start) — it feeds the layout engine, which lays out one block at a time and has no use for a document-wide number. AddressablePiece is the other half: start/end are document-relative, for a caller correlating a piece boundary against something that is addressed in the document’s own space — a comment’s stored character range, another block’s position(), a find_all match. Pairing a block-relative offset with a document-relative string (or the reverse) is exactly the “offset from one space, string from another” bug to_addressable_text’s doc comment describes for whole-document offsets — this type exists so a caller never has to do that arithmetic, and never gets it wrong, one level down inside a single block.

end - start is always 1 for InlineContent::Image and [InlineContent:: FootnoteRef] — the U+FFFC sentinel counts as one character, matching how the document itself counts it — and equals content’s own char count for InlineContent::Text.

Obtained from TextBlock::addressable_inline_pieces.
