Module parallel 

Parallel access patterns for RustAST and PureFile.

Thread Safety Notes

RustAST (syn-based)

syn::File is NOT Send/Sync due to proc_macro2::Span containing raw pointers. This means:

• Cannot share RustAST across threads with Arc
• Cannot use thread::spawn with RustAST

PureFile (span-free)

PureFile is Send + Sync - fully thread-safe! This means:

• Can share with Arc<PureFile> across threads
• Can use rayon parallel iterators directly
• Ideal for parallel code analysis

Practical Patterns for Murmuration

1. PureFile + Arc: Share read-only AST across threads
2. PureFile + COW: Clone-and-modify for parallel mutations
3. Parse-per-thread: Each thread parses source independently
4. Rayon for CPU-bound: Use rayon for parallel iteration on collections
