Function lib_rapid::compsci::compression::huffman::read_from_file

pub fn read_from_file(path: String) -> String

Reads and decodes the message stored in the .hlr and .htlr files.

Arguments

• path - The path to be read from.

Returns

A String containing the decoded message.

Examples

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

let s: &str = "Lorem Ipsum";
let root = get_root(s);
let mut bitvec = BitVec::new();
let mut char_codes: HashMap<char, BitVec> = HashMap::new();
assign_codes(&root, &mut char_codes, &mut bitvec); // 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.
let dec = huffman_decode(&bitvec, &root); // Decodes the BitVec which was created by the last line.
write_to_file("test".to_string(), &enc, &root);
let dec_written = read_from_file("test".to_string());
