Struct HuffmanData 

pub struct HuffmanData {
    pub encoded_data: Vec<u8>,
    pub encoding_map: HashMap<u8, String>,
    pub stats: EncodingStats,
}

Huffman encoded data

Fields

encoded_data: Vec<u8>

The encoded data as a Vec<u8>

encoding_map: HashMap<u8, String>

Encoding map stored as a EncodingMap required for decoding the data

stats: EncodingStats

Encoding stats for the data

Implementations

impl HuffmanData

pub fn new(data: &[u8]) -> Result<HuffmanData, HuffmanError<'static>>

Huffman encodes a Vec<u8> returning a HuffmanData struct

Arguments

• data - A reference to Vec<u8> containing the data you want to encode

Examples

extern crate huff_tree_tap;
use  huff_tree_tap::*;
use std::collections::HashMap;

let data: Vec<u8> = Vec::<u8>::from("this is a test string!");
let huffman_data: HuffmanData = HuffmanData::new(&data).unwrap();
let decoded_data: Vec<u8> = huffman_data.decode().unwrap();
assert_eq!(decoded_data,data);

pub fn decode(&self) -> Result<Vec<u8>, HuffmanError<'static>>

Huffman decodes a HuffmanData struct and returns a decoded Vec<u8>

Arguments

• huffman_encoded_data - A reference to HuffmanData containing the encoded data and encoding map

Examples

extern crate huff_tree_tap;
use  huff_tree_tap::*;
use std::collections::HashMap;

let data: Vec<u8> = Vec::from("this is a test string!");
let huffman_data: HuffmanData = HuffmanData::new(&data).unwrap();
let decoded_data: Vec<u8> = huffman_data.decode().unwrap();
assert_eq!(decoded_data,data);

Trait Implementations
