Struct Mutator 

pub struct Mutator { /* private fields */ }

Mutator for transaction-based code changes.

The Mutator uses the Transaction module to apply changes atomically, snapshotting files before mutation and providing rollback capability.

Implementations

impl Mutator

pub fn new() -> Self

Creates a new mutator.

pub async fn begin_transaction(&mut self) -> Result<()>

Begins a new transaction.

pub async fn apply_step(&mut self, step: &PlanStep) -> Result<()>

Applies a single step in the current transaction.

Snapshots each file before mutation for rollback capability.

pub async fn rollback(&mut self) -> Result<()>

Rolls back the current transaction.

Takes the transaction, rolls back all changes, and returns Ok.

pub async fn commit_transaction(self) -> Result<Uuid>

Commits the current transaction.

Takes the transaction, commits it, and returns the commit ID.

pub fn into_transaction(self) -> Result<Transaction>

Extracts the transaction from the mutator.

This is used when transferring the transaction to another component (e.g., from Mutator to AgentLoop).

pub async fn preview(&self, steps: &[PlanStep]) -> Result<Vec<String>>

Returns preview of changes without applying.
