Implementations§

W: Write,
impl<W> Encoder<W, DefaultLz77Encoder>where W: Write,
sourcepub fn new(inner: W) -> Self
pub fn new(inner: W) -> Self
Makes a new encoder instance.
Encoded DEFLATE stream is written to inner
.
Examples
use std::io::Write;
use libflate::deflate::Encoder;
let mut encoder = Encoder::new(Vec::new());
encoder.write_all(b"Hello World!").unwrap();
assert_eq!(encoder.finish().into_result().unwrap(),

impl<W, E> Encoder<W, E>where W: Write, E: Lz77Encode,
sourcepub fn with_options(inner: W, options: EncodeOptions<E>) -> Self
pub fn with_options(inner: W, options: EncodeOptions<E>) -> Self
Makes a new encoder instance with specified options.
Encoded DEFLATE stream is written to inner
.
Examples
use std::io::Write;
use libflate::deflate::{Encoder, EncodeOptions};
let options = EncodeOptions::new().no_compression();
let mut encoder = Encoder::with_options(Vec::new(), options);
encoder.write_all(b"Hello World!").unwrap();

[1, 12, 0, 243, 255, 72, 101, 108, 108, 111, 32, 87, 111,
114, 108, 100, 33]);
sourcepub fn finish(self) -> Finish<W, Error>
pub fn finish(self) -> Finish<W, Error>
Flushes internal buffer and returns the inner stream.
Examples
use std::io::Write;
use libflate::deflate::Encoder;
let mut encoder = Encoder::new(Vec::new());
encoder.write_all(b"Hello World!").unwrap();
assert_eq!(encoder.finish().into_result().unwrap(),

sourcepub fn as_inner_ref(&self) -> &W
pub fn as_inner_ref(&self) -> &W
Returns the immutable reference to the inner stream.
sourcepub fn as_inner_mut(&mut self) -> &mut W
pub fn as_inner_mut(&mut self) -> &mut W
Returns the mutable reference to the inner stream.
sourcepub fn into_inner(self) -> W
pub fn into_inner(self) -> W
Unwraps the Encoder
, returning the inner stream.
