Struct libflate::deflate::EncodeOptions

pub struct EncodeOptions<E = DefaultLz77Encoder> { /* fields omitted */ }

Options for a DEFLATE encoder.

Methods

impl EncodeOptions<DefaultLz77Encoder>

fn new() -> Self

Makes a default instance.

Examples

use libflate::deflate::{Encoder, EncodeOptions};

let options = EncodeOptions::new();
let encoder = Encoder::with_options(Vec::new(), options);

impl<E> EncodeOptions<E> where
    E: Lz77Encode, 

fn with_lz77(lz77: E) -> Self

Specifies the LZ77 encoder used to compress input data.

Example

use libflate::lz77::DefaultLz77Encoder;
use libflate::deflate::{Encoder, EncodeOptions};

let options = EncodeOptions::with_lz77(DefaultLz77Encoder::new());
let encoder = Encoder::with_options(Vec::new(), options);

fn no_compression(self) -> Self

Disables LZ77 compression.

Example

use libflate::lz77::DefaultLz77Encoder;
use libflate::deflate::{Encoder, EncodeOptions};

let options = EncodeOptions::new().no_compression();
let encoder = Encoder::with_options(Vec::new(), options);

fn block_size(self, size: usize) -> Self

Specifies the hint of the size of a DEFLATE block.

The default value is DEFAULT_BLOCK_SIZE.

Example

use libflate::deflate::{Encoder, EncodeOptions};

let options = EncodeOptions::new().block_size(512 * 1024);
let encoder = Encoder::with_options(Vec::new(), options);

fn fixed_huffman_codes(self) -> Self

Specifies to compress with fixed huffman codes.

Example

use libflate::deflate::{Encoder, EncodeOptions};

let options = EncodeOptions::new().fixed_huffman_codes();
let encoder = Encoder::with_options(Vec::new(), options);
