RFC Pattern Implementation

  • Implemented RFC pattern with ContiguousArray as canonical byte representation
  • Added zero-copy ContiguousArray initializer for HTML types
  • Added Array convenience initializer
  • Updated String initializer to derive from canonical bytes
  • Deprecated legacy .render() methods in favor of RFC pattern

Performance Optimizations

  • Eliminated UTF-8 conversions by using [UInt8] in Configuration (indentation/newline)
  • Added capacity pre-allocation support to HTMLPrinter (reservedCapacity parameter)
  • Optimized attribute value HTML escaping with fast-path detection (~30% faster)
  • Integrated INCITS 4-1986 for ASCII constants
  • Performance: ~3,500 documents/second (~280µs per complete HTML document)

Documentation

  • Updated README with RFC pattern examples
  • Added comprehensive inline documentation
  • Updated performance metrics throughout codebase

Testing

  • Added comprehensive performance tests for attribute escaping
  • Added performance tests for capacity optimization
  • All 198 tests passing

CI/CD

  • Updated CI to use Swift 6.2 for all jobs
  • Adjusted performance test thresholds for CI runners
  • Improved cache key management

Breaking Changes

None - all changes are backward compatible through deprecations.
