Module structural_mutate 

Native Rust structural mutation and mapping.

structural_mutate lets a mutator drive recursion, while structural_map applies callbacks around engine-owned recursion.

Re-exports

pub use super::unchanged::Unchanged;

pub use super::unchanged::UnchangedOr;

Structs

InplaceValue

Engine-issued permission to attempt in-place mutation of one value.

MapValue

Borrowed value passed to structural map and mutation callbacks. A borrowed value shared by structural visit and map callbacks.

MutateCallbacks

A reusable typed-dispatch or callback mutator with shared user state.

MutateContext

State and recursive operations available to a callback-chain mutation.

Mutator

Recursion control passed to a typed #[dispatch(mutate)] handler.

StructuralVarRemap

Identity substitutions for a custom StructuralMutator remapping policy.

Traits

IntoMapper

Conversion into the mapper consumed by structural_map.

IntoMutator

Conversion into the mutator argument accepted by structural_mutate.

MapChainLink

One typed callback in a structural-map tuple.

MapDispatch

Ordered typed replacement dispatch for structural_map.

MutateChainLink

One typed callback in a callback-driven structural mutator.

MutateDispatch

Ordered typed callback dispatch for structural_mutate.

StructuralMutator

A low-level mutator that controls its own recursion.

Functions

structural_map

Transform a structured value graph with ordered replacement callbacks.

structural_mutate

Mutate a structured value with a mutator or typed callback chain.

Type Aliases

CallbackMutator

Recursive mutation operations passed to closure callback chains.
