Makes a new encoder instance.

Encoded ZLIB stream is written to inner.

Examples

use std::io::Write;
use libflate::zlib::Encoder;

let mut encoder = Encoder::new(Vec::new()).unwrap();
encoder.write_all(b"Hello World!").unwrap();

assert_eq!(encoder.finish().into_result().unwrap(),
           [120, 156, 5, 128, 65, 9, 0, 0, 8, 3, 171, 104, 27, 27, 88, 64, 127,
            7, 131, 245, 127, 140, 121, 80, 173, 204, 117, 0, 28, 73, 4, 62]);

Makes a new encoder instance with specified options.

Encoded ZLIB stream is written to inner.

Examples

use std::io::Write;
use libflate::zlib::{Encoder, EncodeOptions};

let options = EncodeOptions::new().no_compression();
let mut encoder = Encoder::with_options(Vec::new(), options).unwrap();
encoder.write_all(b"Hello World!").unwrap();

assert_eq!(encoder.finish().into_result().unwrap(),
           [120, 1, 1, 12, 0, 243, 255, 72, 101, 108, 108, 111, 32, 87, 111,
            114, 108, 100, 33, 28, 73, 4, 62]);

Returns the header of the ZLIB stream.

Examples

use libflate::zlib::{Encoder, Lz77WindowSize};

let encoder = Encoder::new(Vec::new()).unwrap();
assert_eq!(encoder.header().window_size(), Lz77WindowSize::KB32);

Writes the ZLIB trailer and returns the inner stream.

Examples

use std::io::Write;
use libflate::zlib::Encoder;

let mut encoder = Encoder::new(Vec::new()).unwrap();
encoder.write_all(b"Hello World!").unwrap();

assert_eq!(encoder.finish().into_result().unwrap(),
           [120, 156, 5, 128, 65, 9, 0, 0, 8, 3, 171, 104, 27, 27, 88, 64, 127,
            7, 131, 245, 127, 140, 121, 80, 173, 204, 117, 0, 28, 73, 4, 62]);

Note

If you are not concerned the result of this encoding, it may be convenient to use AutoFinishUnchecked instead of the explicit invocation of this method.

use std::io;
use libflate::finish::AutoFinishUnchecked;
use libflate::zlib::Encoder;

let plain = b"Hello World!";
let mut buf = Vec::new();
let mut encoder = AutoFinishUnchecked::new(Encoder::new(&mut buf).unwrap());
io::copy(&mut &plain[..], &mut encoder).unwrap();

Returns the immutable reference to the inner stream.

Returns the mutable reference to the inner stream.

Unwraps the Encoder, returning the inner stream.
