Implementations§

source§

impl DefaultLz77Encoder

source

pub fn new() -> Self

Makes a new encoder instance.

Examples
use libflate::deflate;
use libflate::lz77::{self, Lz77Encode, DefaultLz77Encoder};

let lz77 = DefaultLz77Encoder::new();
assert_eq!(lz77.window_size(), lz77::MAX_WINDOW_SIZE);

let options = deflate::EncodeOptions::with_lz77(lz77);
let _deflate = deflate::Encoder::with_options(Vec::new(), options);
source

pub fn with_window_size(size: u16) -> Self

Makes a new encoder instance with specified window size.

Larger window size is prefered to raise compression ratio, but it may require more working memory to encode and decode data.

Examples
use libflate::deflate;
use libflate::lz77::{self, Lz77Encode, DefaultLz77Encoder};

let lz77 = DefaultLz77Encoder::with_window_size(1024);
assert_eq!(lz77.window_size(), 1024);

let options = deflate::EncodeOptions::with_lz77(lz77);
let _deflate = deflate::Encoder::with_options(Vec::new(), options);
