[−][src]Struct libflate::zlib::Decoder

pub struct Decoder<R> { /* fields omitted */ }

ZLIB decoder.

Methods

impl<R> Decoder<R> where
    R: Read, [src]

pub fn new(inner: R) -> Result<Self>[src]

Makes a new decoder instance.

inner is to be decoded ZLIB stream.

Examples

use std::io::Read;
use libflate::zlib::Decoder;

let encoded_data = [120, 156, 243, 72, 205, 201, 201, 87, 8, 207, 47,
                    202, 73, 81, 4, 0, 28, 73, 4, 62];

let mut decoder = Decoder::new(&encoded_data[..]).unwrap();
let mut buf = Vec::new();
decoder.read_to_end(&mut buf).unwrap();

assert_eq!(buf, b"Hello World!");

pub fn header(&self) -> &Header[src]

Returns the header of the ZLIB stream.

Examples

use libflate::zlib::{Decoder, CompressionLevel};

let encoded_data = [120, 156, 243, 72, 205, 201, 201, 87, 8, 207, 47,
                    202, 73, 81, 4, 0, 28, 73, 4, 62];

let decoder = Decoder::new(&encoded_data[..]).unwrap();
assert_eq!(decoder.header().compression_level(),
           CompressionLevel::Default);

pub fn as_inner_ref(&self) -> &R[src]

Returns the immutable reference to the inner stream.

pub fn as_inner_mut(&mut self) -> &mut R[src]

Returns the mutable reference to the inner stream.

pub fn into_inner(self) -> R[src]

Unwraps this Decoder, returning the underlying reader.

Examples

use std::io::Cursor;
use libflate::zlib::Decoder;

let encoded_data = [120, 156, 243, 72, 205, 201, 201, 87, 8, 207, 47,
                    202, 73, 81, 4, 0, 28, 73, 4, 62];

let decoder = Decoder::new(Cursor::new(&encoded_data)).unwrap();
assert_eq!(decoder.into_inner().into_inner(), &encoded_data);
