Module text3 

Text shaping, line breaking (Knuth-Plass), and inline formatting. Text layout and shaping system.

This module provides text shaping, inline layout, editing, selection, and font caching. Submodules:

• cache: unified text layout cache (UnifiedLayout)
• default: default text shaping and line-breaking
• edit: text editing operations
• glyphs: glyph positioning and cluster mapping
• knuth_plass: Knuth-Plass line-breaking algorithm
• mock_fonts: built-in test fonts with exactly known metrics
• script: Unicode script detection
• selection: text selection and cursor utilities

Modules

cache

Core types and layout pipeline for the text/inline formatting context.

default

Default / concrete implementations of the text3 trait abstractions.

edit

Pure functions for editing a Vec<InlineContent> based on selections.

glyphs

A helper module to extract final, absolute glyph positions from a layout. This is useful for renderers that work with simple lists of glyphs.

knuth_plass

An implementation of the Knuth-Plass line-breaking algorithm for simple rectangular layouts.

mock_fonts

Built-in MOCK FONTS with fully controlled metrics.

script

Unicode script detection and language identification for text shaping

selection

Text selection helper functions
