Struct cmprsd::huffman::CompressedData

pub struct CompressedData {
    pub bits: Vec<u8>,
    pub meaningful_bits: u8,
}

Struct that represents compressed data.

Fields

bits: Vec<u8>

Vector of compressed bytes. each compressed block is stored at a bit level.
TODO: allow to use u8, u16, u32, u64 :

meaningful_bits: u8

As we store blocks of 8 bits, not all 8 bits are used at all times. We therefore need a way to store how many bits are used or not used in the last byte. Currently I store how many of these bits are used.

Implementations

impl CompressedData

pub fn get_empty() -> CompressedData

Returns a compressed data entity which stores 0 bits.

pub fn from_bits_as_u8(bits_as_u8: &[u8]) -> CompressedData

Take as input a vector of 0s and 1s and store them as bits.

pub fn len(&self) -> usize

size of the compressed data in bits

pub fn is_empty(&self) -> bool

pub fn pad(&mut self, padding_size: u8)

Helper function to pad a block of bits. Usefull when combining blocks.

pub fn add(&mut self, other: &CompressedData)

Append bits of the other compressed data to self.

Trait Implementations

impl Clone for CompressedData

fn clone(&self) -> CompressedData

Returns a copy of the value.

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

Performs copy-assignment from source.
