Struct Segment 

pub struct Segment {
    pub kind: SegmentKind,
    pub range: TextRange,
    pub lowered_range: TextRange,
    pub header_start: Option<TextSize>,
}

One contiguous slice of the file. Produced by segment_file; segments tile the file in source order.

Fields

kind: SegmentKind

range: TextRange

The byte range this segment covers, doc-block extension included. Ranges TILE the file (offset bookkeeping); the text a consumer should PARSE is lowered_range.

lowered_range: TextRange

The range to parse for this segment: range extended through the trailing trivia up to the NEXT segment’s header token (or EOF). The whole-file parse absorbs the trivia before a knot header — blank lines, comments, and the next knot’s /// doc block — into the PRECEDING knot’s node, so a fragment must end at the next header for its node ranges to match the whole-file tree byte-for-byte. Where the next boundary carries a doc block, this makes adjacent lowered_ranges OVERLAP on the doc bytes: the doc block is trailing trivia to this segment and doc attachment to the next — both readings are what the whole-file parse does.

header_start: Option<TextSize>

The byte offset of the header’s first = token — the position the whole-file parse gives the corresponding KNOT_HEADER/ STITCH_HEADER node. None for the header segment.
