One grapheme cluster in the input. More...

#include <shaped_text.hpp>

Public Attributes
std::uint32_t	utf8_start = 0
	UTF-8 byte offset (start, inclusive).
std::uint32_t	utf8_end = 0
	UTF-8 byte offset (end, exclusive).
std::uint32_t	run_index = 0
	Index into ShapedText::runs.
std::uint32_t	glyph_start = 0
	First glyph in that run; 0 until glyph buffers are populated.
std::uint32_t	glyph_count = 0
	Glyph count for this cluster; 0 until glyph buffers are populated.

Detailed Description

One grapheme cluster in the input.

The planner builds these with the shared cluster_step() walker so editor movement, selection, and text measurement use the same UTF-8 cluster ranges.
