Struct GenTree

pub struct GenTree<T> { /* private fields */ }

Implementations

impl<T> GenTree<T>

pub fn new() -> Self

pub fn root(&self) -> &Position

pub fn size(&self) -> usize

pub fn num_children(&self, pos: &Position) -> usize

pub fn is_some(&self, pos: &Position) -> bool

pub fn is_empty(&self) -> bool

pub fn mut_root(&self, data: T)

pub fn depth(&self, pos: &Position) -> usize

The number of levels from a given node to the root

pub fn is_none(&self, position: &Position) -> bool

pub fn parent<'a>(&'a self, position: &Position) -> Option<Ref<'a, Position>>

Yields a dynamic reference guard to the parent token inside the arena.

pub fn children(&self, position: &Position) -> Ref<'_, Vec<Position>>

pub fn get_data<'a>(&'a self, position: &Position) -> Option<Ref<'a, T>>

pub fn add_child(&self, parent_pos: &Position, data: T) -> Position

pub fn remove(&self, position: Position) -> Option<T>

Explicitly consumes the token, destroying it from the caller’s frame permanently.
