Trait Implementations

impl Clone for Tree

fn clone(&self) -> Tree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tree

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Tree

fn deserialize<__D>( __deserializer: __D, ) -> Result<Tree, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Index<&String> for Tree

type Output = Arc<Node>

The returned type after indexing.

fn index(&self, index: &String) -> &<Tree as Index<&String>>::Output

Performs the indexing (container[index]) operation.

impl Index<&str> for Tree

type Output = Arc<Node>

The returned type after indexing.

fn index(&self, index: &str) -> &<Tree as Index<&str>>::Output

Performs the indexing (container[index]) operation.

impl PartialEq for Tree

fn eq(&self, other: &Tree) -> 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.

impl Serialize for Tree

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
