Struct libflate::gzip::MultiDecoder [−][src]
pub struct MultiDecoder<R> { /* fields omitted */ }
Expand description
A decoder that decodes all members in a GZIP stream.
Implementations
Makes a new decoder instance.
inner
is to be decoded GZIP stream.
Examples
use std::io::Read;
use libflate::gzip::MultiDecoder;
let mut encoded_data = Vec::new();
// Add a member (a GZIP binary that represents "Hello ")
encoded_data.extend(&[31, 139, 8, 0, 51, 206, 75, 90, 0, 3, 5, 128, 49, 9, 0, 0, 0, 194, 170, 24,
199, 34, 126, 3, 251, 127, 163, 131, 71, 192, 252, 45, 234, 6, 0, 0, 0][..]);
// Add another member (a GZIP binary that represents "World!")
encoded_data.extend(&[31, 139, 8, 0, 227, 207, 75, 90, 0, 3, 5, 128, 49, 9, 0, 0, 0, 194, 178, 152,
202, 2, 158, 130, 96, 255, 99, 120, 111, 4, 222, 157, 40, 118, 6, 0, 0, 0][..]);
let mut decoder = MultiDecoder::new(&encoded_data[..]).unwrap();
let mut buf = Vec::new();
decoder.read_to_end(&mut buf).unwrap();
assert_eq!(buf, b"Hello World!");
Returns the header of the current member in the GZIP stream.
Examples
use libflate::gzip::{MultiDecoder, 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 = MultiDecoder::new(&encoded_data[..]).unwrap();
assert_eq!(decoder.header().os(), Os::Unix);
Returns the immutable reference to the inner stream.
Returns the mutable reference to the inner stream.
Unwraps this MultiDecoder
, returning the underlying reader.
Examples
use std::io::Cursor;
use libflate::gzip::MultiDecoder;
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 = MultiDecoder::new(Cursor::new(&encoded_data[..])).unwrap();
assert_eq!(decoder.into_inner().into_inner(), &encoded_data[..]);
