Struct Plan 

pub struct Plan {
    pub goal: String,
    pub steps: Vec<PlanStep>,
}

An ordered, harness-owned task plan: a top-level goal decomposed into steps.

Fields

goal: String

The overall task this plan accomplishes (re-surfaced each turn to fight goal-drift / “lost in the middle” on long runs).

steps: Vec<PlanStep>

Ordered subgoals.

Implementations

impl Plan

pub fn new( goal: impl Into<String>, steps: impl IntoIterator<Item = impl Into<String>>, ) -> Self

Build a plan from a goal and an ordered list of step descriptions.

pub fn current(&self) -> Option<usize>

Index of the first non-terminal (Pending/Active) step — the one the executor should be working on. None when every step is Done/Failed.

pub fn is_complete(&self) -> bool

Whether every step reached a terminal status (Done or Failed).

pub fn all_done(&self) -> bool

Whether all steps are specifically Done (the success condition).

pub fn set_status(&mut self, idx: usize, status: StepStatus) -> bool

Mark the step at idx, returning false if idx is out of range (no panic — library code must not index blindly).

pub fn render(&self) -> String

Deterministic, cache-stable rendering for re-injection into the prompt near the context tail (goal recitation). The harness owns this; the model reads it and only requests status flips — it never reproduces the list to make progress.

Trait Implementations

impl Clone for Plan

fn clone(&self) -> Plan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Plan

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

Formats the value using the given formatter.

impl Eq for Plan

impl PartialEq for Plan

fn eq(&self, other: &Plan) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
