DJLS Ruff AST

Use this before editing djls-extraction or code that consumes Ruff Python AST nodes.

Known API shapes

  • Parse modules with ruff_python_parser::parse_module(source) and call .into_syntax() for ModModule AST.
  • Function defaults are per-parameter. There is no top-level defaults field.
    • Use ParameterWithDefault { parameter, default: Option<Box<Expr>> }.
  • StmtWhile.test, StmtIf.test, and similar fields are Box<Expr>.
    • Dereference with &* for pattern matching.
  • FStringValue uses .iter(), not .parts(), for FStringPart iteration.
  • ExceptHandler::ExceptHandler is irrefutable.
    • Use let, not if let.
