Struct ego_tree::Tree

pub struct Tree<T> { /* fields omitted */ }

Vec-backed ID-tree.

Always contains at least a root node.

Trait Implementations

impl<T> PartialEq<Tree<T>> for Tree<T> where     T: PartialEq,

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<T> Eq for Tree<T> where     T: Eq,

impl<T> Clone for Tree<T> where     T: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> IntoIterator for Tree<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: Debug> Debug for Tree<T>

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

Formats the value using the given formatter.

impl<T> Hash for Tree<T> where     T: Hash,

fn hash<H>(&self, state: &mut H) where     H: Hasher,

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,
