oxipdf-ir

Intermediate representation types for the oxipdf PDF engine.

This crate defines the StyledTree IR that serves as the input contract for the oxipdf rendering pipeline. Consumers construct a StyledTree from their domain AST and submit it to the engine for layout and emission.

What's Inside

• StyledTree and StyledTreeBuilder — the validated IR tree
• Node, NodeId, ContentVariant — node types and content
• ResolvedStyle — fully resolved styles (no inheritance, no cascade)
• Pt, Dimension, LengthPercentage — canonical unit types
• IrVersion — schema versioning with forward-compatibility rules
• SemanticRole — semantic markup for theming

IR Schema Versioning

The IR schema is versioned via IrVersion. Same major version is forward-compatible (older tree, newer engine). Different major versions are incompatible.
