Struct inflate::DeflateDecoder
[−]
[src]
pub struct DeflateDecoder<R> { /* fields omitted */ }A DEFLATE decoder/decompressor.
This structure implements a Read interface and takes a stream of compressed data that
implements the Read trait as input,
provoding the decompressed data when read from.
Example
use std::io::Read; use inflate::DeflateDecoder; const TEST_STRING: &'static str = "Hello, world"; let encoded = vec![243, 72, 205, 201, 201, 215, 81, 40, 207, 47, 202, 73, 1, 0]; let mut decoder = DeflateDecoder::new(&encoded[..]); let mut output = Vec::new(); let status = decoder.read_to_end(&mut output); assert_eq!(String::from_utf8(output).unwrap(), TEST_STRING);
Methods
impl<R: Read> DeflateDecoder<R>[src]
fn new(reader: R) -> DeflateDecoder<R>[src]
Create a new Deflatedecoderbuf to read from a raw deflate stream.
fn from_zlib(reader: R) -> DeflateDecoder<R>[src]
Create a new DeflateDecoderbuf that reads from a zlib wrapped deflate stream.
fn from_zlib_no_checksum(reader: R) -> DeflateDecoder<R>[src]
Create a new DeflateDecoderbuf that reads from a zlib wrapped deflate stream.
without calculating and validating the checksum.
fn reset(&mut self, r: R) -> R[src]
Resets the decompressor, and replaces the current inner BufRead instance by r.
without doing any extra reallocations.
Note that this function doesn't ensure that all data has been output.
fn get_ref(&self) -> &R[src]
Returns a reference to the underlying reader.
fn get_mut(&mut self) -> &mut R[src]
Returns a mutable reference to the underlying reader.
Note that mutation of the reader may cause surprising results if the decoder is going to keep being used.
fn into_inner(self) -> R[src]
Returns the total number of bytes output from this decoder.
impl<R> DeflateDecoder<R>[src]
fn reset_data(&mut self)[src]
Resets the decoder, but continue to read from the same reader.
Note that this function doesn't ensure that all data has been output.
fn total_in(&self) -> u64[src]
Returns the total bytes read from the underlying reader.
fn total_out(&self) -> u64[src]
Returns the total number of bytes output from this decoder.
fn current_checksum(&self) -> u32[src]
Returns the calculated checksum value of the currently decoded data.
Will return 0 for cases where the checksum is not validated.
