Struct Huffman 

pub struct Huffman { /* private fields */ }

Holds the data needed to (de)compress.

• Compress with Self::compress
• Decompress with Self::decompress

Implementations

impl Huffman

pub fn new(frequency_table: &[usize; 256]) -> Self

Initializes the huffman interface using the provided frequency table.

pub fn new_from_data(data: &[u8]) -> Self

Creates the Huffman frequency table from the provided data and initializes from it.

pub fn calculate_freq_table(table: &mut [usize; 256], data: &[u8])

Calculates the frequency table from the provided data.

pub fn compress(&self, data: &[u8]) -> Vec<u8>

Compresses the provided data.

pub fn decompress(&self, data: &[u8]) -> Vec<u8>

Decompresses the provided data.

Trait Implementations

impl Clone for Huffman

fn clone(&self) -> Huffman

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Huffman

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

Formats the value using the given formatter.

impl PartialEq for Huffman

fn eq(&self, other: &Huffman) -> 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 Eq for Huffman
