Implementations§

source§

impl<R> Decoder<R>where R: Read,

source

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

Makes a new decoder instance.

inner is to be decoded GZIP stream.

Examples
use std::io::Read;
use libflate::gzip::Decoder;

let encoded_data = [31, 139, 8, 0, 123, 0, 0, 0, 0, 3, 1, 12, 0, 243, 255,
                    72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33,
                    163, 28, 41, 28, 12, 0, 0, 0];

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!");
source

pub fn header(&self) -> &Header

Returns the header of the GZIP stream.

Examples
use libflate::gzip::{Decoder, Os};

let encoded_data = [31, 139, 8, 0, 123, 0, 0, 0, 0, 3, 1, 12, 0, 243, 255,
                    72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33,
                    163, 28, 41, 28, 12, 0, 0, 0];

let decoder = Decoder::new(&encoded_data[..]).unwrap();
assert_eq!(decoder.header().os(), Os::Unix);
source

pub fn as_inner_ref(&self) -> &R

Returns the immutable reference to the inner stream.

source

pub fn as_inner_mut(&mut self) -> &mut R

Returns the mutable reference to the inner stream.

source

pub fn into_inner(self) -> R

Unwraps this Decoder, returning the underlying reader.

Examples
use std::io::Cursor;
use libflate::gzip::Decoder;

let encoded_data = [31, 139, 8, 0, 123, 0, 0, 0, 0, 3, 1, 12, 0, 243, 255,
                    72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33,
                    163, 28, 41, 28, 12, 0, 0, 0];

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