pub struct GoalTree {
    pub goals: Vec<Goal>,
}

A tree of goals with parent-child traversal.

Fields

goals: Vec<Goal>

Implementations

impl GoalTree

pub fn new() -> Self

Create an empty goal tree.

pub fn add(&mut self, goal: Goal)

Add a goal to the tree.

pub fn find(&self, id: &str) -> Option<&Goal>

Find a goal by ID.

pub fn find_mut(&mut self, id: &str) -> Option<&mut Goal>

Find a goal by ID (mutable).

pub fn roots(&self) -> Vec<&Goal>

Return all root goals (those with no parent).

pub fn children(&self, parent_id: &str) -> Vec<&Goal>

Return all direct children of the given goal.

pub fn descendants(&self, parent_id: &str) -> Vec<&Goal>

Return all descendants of the given goal (depth-first).

pub fn by_status(&self, status: GoalStatus) -> Vec<&Goal>

Return goals filtered by status.
