Struct EmptyNode 

pub struct EmptyNode {}

EmptyNode is an implementation of trait Node that contains nothing.

Such a node store nothing but is just a place holder.

Implementations

impl EmptyNode

pub fn new() -> EmptyNode

Creates an EmptyNode.

Trait Implementations

impl Clone for EmptyNode

fn clone(&self) -> EmptyNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EmptyNode

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

Formats the value using the given formatter.

impl Default for EmptyNode

fn default() -> EmptyNode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EmptyNode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EmptyNode

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

Formats the value using the given formatter.

impl Eq for EmptyNode

impl PartialEq for EmptyNode

fn eq(&self, other: &EmptyNode) -> 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 EmptyNode

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.
