Struct PlanExecutor 

pub struct PlanExecutor { /* private fields */ }

Dry-run ActionExecutor — never mutates state.

Dispatch is registry-validated (M4-B S1): every action’s Action::name is looked up in the embedded plugin Registry so unknown action kinds surface as ExecError::UnknownAction with the same taxonomy as crate::execute::FsExecutor. The planner keeps its own dry-run implementations (the Tier-1 crate::plugin::ActionPlugin set is wet-run only) and uses the registry purely as a name oracle.

Useful for grex plan, CI validation, and unit-testing pack semantics. Safe to call across threads; Clone bumps the inner Arc refcount.

Implementations

impl PlanExecutor

pub fn new() -> Self

Construct a fresh planner backed by the full Tier-1 built-in registry (Registry::bootstrap). Matches the pre-M4-B constructor shape so existing test sites continue to compile.

pub fn with_registry(registry: Arc<Registry>) -> Self

Construct a planner backed by an explicit registry. Primarily for tests that want to exercise ExecError::UnknownAction or share a single registry instance with the wet-run executor.

Trait Implementations

impl ActionExecutor for PlanExecutor

fn name(&self) -> &'static str

Short stable identifier for the implementation. Used in logs / audit trails. Never rendered to end users as a translation key.

fn execute( &self, action: &Action, ctx: &ExecCtx<'_>, ) -> Result<ExecStep, ExecError>

Execute a single Action against ctx.

impl Clone for PlanExecutor

fn clone(&self) -> PlanExecutor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PlanExecutor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PlanExecutor

fn default() -> Self

Returns the “default value” for a type.
