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!");
sourcepub fn header(&self) -> &Header
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,

let decoder = Decoder::new(&encoded_data[..]).unwrap();
assert_eq!(decoder.header().os(), Os::Unix);
sourcepub fn as_inner_ref(&self) -> &R
pub fn as_inner_ref(&self) -> &R
Returns the immutable reference to the inner stream.
sourcepub fn as_inner_mut(&mut self) -> &mut R
pub fn as_inner_mut(&mut self) -> &mut R
Returns the mutable reference to the inner stream.
sourcepub fn into_inner(self) -> R
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,
