Trait ASTRegApply 

pub trait ASTRegApply: Mutation {
    // Required method
    fn apply_to_registry(
        &self,
        ctx: &mut ASTMutationContext<'_>,
    ) -> MutationResult;
}

Trait for mutations that can be applied to ASTRegistry

Extends the base Mutation trait with registry-based execution. This is the primary execution path for the new AST-centric architecture.

Implementing

Mutations that want to support registry-based execution should:

1. Implement this trait
2. Use ctx.lookup() to find target symbols
3. Use ctx.get_ast_mut() to modify AST
4. Use ctx.emit_*() to record changes

Fallback

If a mutation doesn’t implement this trait, ASTMutationEngine will return no changes. The legacy apply(&mut PureFile) path remains available for backward compatibility.

Required Methods

fn apply_to_registry(&self, ctx: &mut ASTMutationContext<'_>) -> MutationResult

Apply this mutation to the ASTRegistry

Arguments

• ctx - Mutable context providing access to registries and event emission

Returns

MutationResult indicating the number of changes made

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
