Function lib_rapid::compsci::compression::huffman::huffman_encode

pub fn huffman_encode(s: &str, char_codes: &mut HashMap<char, BitVec>) -> BitVec

Encodes a string.

Arguments

• s - The string to be encoded.
• char_codes - The assigned Huffman codes of the characters.

Returns

A BitVec which contains the Huffman encoded string.

Examples

use lib_rapid::compsci::compression::huffman::{get_root, assign_codes, huffman_encode};
use bit_vec::BitVec;
use std::collections::HashMap;

let s = "Lorem Ipsum";
let root = get_root(s);
let mut char_codes:HashMap<char, BitVec> = HashMap::new();
assign_codes(&root, &mut char_codes, &mut BitVec::new()); // Assigns codes to characters of s and stores them in char_codes.

let enc = huffman_encode(s, &mut char_codes); // Encodes the String s into enc.
