Struct libflate::non_blocking::deflate::Decoder

[+] Show declaration

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

[−] Expand description

DEFLATE decoder which supports non-blocking I/O.

Implementations

impl<R: Read> Decoder<R>[−]

pub fn new(inner: R) -> Self[−]

Makes a new decoder instance.

inner is to be decoded DEFLATE stream.

Examples

use std::io::{Cursor, Read};
use libflate::non_blocking::deflate::Decoder;

let encoded_data = [243, 72, 205, 201, 201, 87, 8, 207, 47, 202, 73, 81, 4, 0];
let mut decoder = Decoder::new(&encoded_data[..]);
let mut buf = Vec::new();
decoder.read_to_end(&mut buf).unwrap();

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

pub fn as_inner_ref(&self) -> &R[−]

Returns the immutable reference to the inner stream.

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

Returns the mutable reference to the inner stream.

pub fn into_inner(self) -> R[−]

Unwraps this Decoder, returning the underlying reader.

Examples

use std::io::Cursor;
use libflate::non_blocking::deflate::Decoder;

let encoded_data = [243, 72, 205, 201, 201, 87, 8, 207, 47, 202, 73, 81, 4, 0];
let decoder = Decoder::new(Cursor::new(&encoded_data));
assert_eq!(decoder.into_inner().into_inner(), &encoded_data);

fn fmt(&self, f: &mut Formatter<'_>) -> Result[−]

Formats the value using the given formatter.

impl<R: Read> Read for Decoder<R>[+]

[+] Show hidden undocumented items

fn read(&mut self, buf: &mut [u8]) -> Result<usize>[−]

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

pub fn read_vectored(
    &mut self,
    bufs: &mut [IoSliceMut<'_>]
) -> Result<usize, Error>[−]

Like read, except that it reads into a slice of buffers.

pub fn is_read_vectored(&self) -> bool[−]

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

pub unsafe fn initializer(&self) -> Initializer[−]

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

pub fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>[−]

Read all bytes until EOF in this source, placing them into buf.

pub fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>[−]

Read all bytes until EOF in this source, appending them to buf.

pub fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>[−]

Read the exact number of bytes required to fill buf.

pub fn by_ref(&mut self) -> &mut Self[−]

Creates a “by reference” adaptor for this instance of Read.

pub fn bytes(self) -> Bytes<Self>[−]

Transforms this Read instance to an Iterator over its bytes.

pub fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, [−]

Creates an adaptor which will chain this stream with another.

pub fn take(self, limit: u64) -> Take<Self>[−]

Creates an adaptor which will read at most limit bytes from it.
