Enum NodeKind 

pub enum NodeKind {
    Branch,
    Leaf,
}

Tree node kind.

Variants

Branch

A branch is a node that can have children.

Leaf

A leaf is a node that cannot have children.

Implementations

impl NodeKind

pub fn is_branch(&self) -> bool

Whether the node is a branch.

pub fn is_leaf(&self) -> bool

Whether the node is a leaf.

Trait Implementations

impl Clone for NodeKind

fn clone(&self) -> NodeKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NodeKind

impl Debug for NodeKind

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

Formats the value using the given formatter.

impl Eq for NodeKind

impl PartialEq for NodeKind

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