[−][src]Struct libflate::deflate::Encoder
DEFLATE encoder.
Methods
impl<W> Encoder<W, DefaultLz77Encoder> where
W: Write,
[src]
W: Write,
pub fn new(inner: W) -> Self
[src]
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(), [5, 192, 49, 13, 0, 0, 8, 3, 65, 43, 224, 6, 7, 24, 128, 237, 147, 38, 245, 63, 244, 230, 65, 181, 50, 215, 1]);
impl<W, E> Encoder<W, E> where
W: Write,
E: Lz77Encode,
[src]
W: Write,
E: Lz77Encode,
pub fn with_options(inner: W, options: EncodeOptions<E>) -> Self
[src]
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(); assert_eq!(encoder.finish().into_result().unwrap(), [1, 12, 0, 243, 255, 72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33]);
pub fn finish(self) -> Finish<W, Error>
[src]
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(), [5, 192, 49, 13, 0, 0, 8, 3, 65, 43, 224, 6, 7, 24, 128, 237, 147, 38, 245, 63, 244, 230, 65, 181, 50, 215, 1]);
pub fn as_inner_ref(&self) -> &W
[src]
Returns the immutable reference to the inner stream.
pub fn as_inner_mut(&mut self) -> &mut W
[src]
Returns the mutable reference to the inner stream.
pub fn into_inner(self) -> W
[src]
Unwraps the Encoder
, returning the inner stream.
