Struct HuffmanNode

Source

pub struct HuffmanNode {
    pub symbol: Option<u8>,
    pub freq: u32,
    pub left: Option<Box<HuffmanNode>>,
    pub right: Option<Box<HuffmanNode>>,
}

Expand description

A node in a Huffman tree.

Fields§

§symbol: Option<u8>

Present only on leaf nodes; the symbol value.

§freq: u32

Aggregate frequency of the subtree rooted here.

§left: Option<Box<HuffmanNode>>

Left child (lower-frequency subtree).

§right: Option<Box<HuffmanNode>>

Right child (higher-frequency subtree).

Implementations§

Source §

impl HuffmanNode

Source

pub fn is_leaf(&self) -> bool

Returns true when this node is a leaf (holds a symbol, has no children).
