Struct Node 

pub struct Node {
    pub weight: u32,
    pub depth: u8,
    pub syms: u32,
    pub node_data: NodeData,
}

Huffman codes are built from weights derived from a tree structure of these nodes.

Fields

weight: u32

The weight of the node is based on the frequency of the symbols under this node

depth: u8

The depth of the node in the tree

syms: u32

node_data: NodeData

The data associated with this node (either a leaf or a node that (eventually) has leaves)

Implementations

impl Node

pub fn new(weight: u32, depth: u8, syms: u32, node_data: NodeData) -> Node

Create a new node

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Node

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

Formats the value using the given formatter.

impl Ord for Node

fn cmp(&self, other: &Self) -> Ordering

Sort Nodes by decreasing weight and decreasing symbol value

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Node

fn eq(&self, other: &Self) -> 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 PartialOrd for Node

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

Sort Nodes by decreasing weight and decreasing symbol value

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
