Crate xamlx 

Rust port of the backend-independent part of XamlX, the XAML compiler library by Nikita Tsukanov (MIT, see external/XamlX/NOTICE.md).

The crate mirrors the upstream layout module for module:

Module	Upstream	Contents
ast	Ast/	AST nodes, visitors, type/property references, intrinsics
parsers	Parsers/	XML based XAML parser and the markup extension parser
type_system	TypeSystem/	the type system abstraction and its helpers
transform	Transform/	transformation context, configuration and all AST transformers
emit	Emit/	backend-agnostic emit contracts
compiler	Compiler/	the backend-independent compiler driver
diagnostics	Diagnostics/	diagnostics and their severity
exceptions	Exceptions.cs	the error type

The IL backend (IL/) is not part of the port. Upstream AST nodes implement the IL emitting interfaces directly; here the nodes carry only their data, and a backend supplies node emitters (emit::IXamlAstNodeEmitter) for them.

Conventions

• C# interfaces keep their I prefix as trait names and are used through Rc<dyn ...> handles; a C# property named Type becomes type_.
• Nodes are mutable through Cell/RefCell fields, which keeps the upstream in-place visitor semantics and node identity.
• Exceptions become XamlResult values carrying an XamlError.

Macros

xaml_ast_node_members

Implements the bookkeeping members of IXamlAstNode inside an impl block.
