Prepared Text Types

Prepared data is the main value produced by the core engine. These types describe what was measured and how later line walking can reuse it.

`PreparedText`

Use PreparedText when you created it with Prepare and only need aggregate layout operations.

Member	Meaning
`Font`	The font string used for measurement.
`WhiteSpace`	The white-space mode used during preparation.
`DiscretionaryHyphenWidth`	Width of the inserted hyphen when a soft hyphen break is taken.
`TabStopAdvance`	Width of one tab stop, derived from eight measured spaces.

Use PreparedTextWithSegments when you created it with PrepareWithSegments and need richer output.

Member	Meaning
`Segments`	Segment text after analysis and normalization.
`Widths`	Measured width of each segment.
`LineEndFitAdvances`	Width contribution used when deciding whether a segment still fits at line end.
`LineEndPaintAdvances`	Width contribution used when reporting painted width at line end.
`Kinds`	`SegmentBreakKind` for each segment.
`BreakableWidths`	Per-grapheme widths for breakable runs that can wrap internally.
`BreakablePrefixWidths`	Prefix widths for the same breakable runs.
`Chunks`	Hard-break chunk boundaries.
`SimpleLineWalkFastPath`	Indicates whether the simplified line walker can be used internally.
`SegmentLevels`	Optional bidi level per segment for mixed-direction text.

PreparedLineChunk is an advanced type that reflects hard-break chunk boundaries:

Member	Meaning
`StartSegmentIndex`	First segment in the chunk
`EndSegmentIndex`	End of the chunk before the hard break
`ConsumedEndSegmentIndex`	The cursor position after the break is consumed

Most callers do not need Chunks directly, but they are useful when reasoning about forced line boundaries and diagnostics.

Type	Meaning
`LayoutCursor`	Segment + grapheme position for streaming layout
`LayoutResult`	Aggregate line count and height
`LayoutLine`	Materialized text, width, start cursor, and end cursor for one line
`LayoutLineRange`	Width and cursor range for one line without materialized text
`LayoutLinesResult`	Aggregate result plus a line collection
`PrepareProfile`	Coarse timing split for analysis and measurement
