Struct libflate_lz77::DefaultLz77Encoder
source · pub struct DefaultLz77Encoder { /* private fields */ }
Expand description
A Lz77Encode
implementation used by default.
Implementations§
source§impl DefaultLz77Encoder
impl DefaultLz77Encoder
sourcepub fn new() -> Self
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);
sourcepub fn with_window_size(size: u16) -> Self
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);
