Module engine 

AST Mutation Engine

Registry-centric mutation execution without file I/O.

Components

• ASTMutationEngine: Core execution engine
• ASTMutationContext: Context passed to mutations
• ASTRegApply: Trait for registry-based mutation execution
• MutationEvent: Events emitted during mutation
• SourceDumper: Type-safe pipeline for source generation (Generator → Dumper)
• RegistryGenerator: Generate files from ASTRegistry + SymbolRegistry (SymbolPath-based)
• modified_files: Content-based modified file detection

Implementations

The impls module contains ASTRegApply implementations for mutations defined in ryo-mutations.

Re-exports

pub use impls::add_item_v2;

pub use impls::create_mod_v2;

pub use impls::remove_item_v2;
