Struct Lzma2Reader 

pub struct Lzma2Reader<R> { /* private fields */ }

A single-threaded LZMA2 decompressor.

Examples

use std::io::Read;

use lzma_rust2::{Lzma2Reader, LzmaOptions};

let compressed: Vec<u8> = vec![
    1, 0, 12, 72, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100, 33, 0,
];
let mut reader = Lzma2Reader::new(compressed.as_slice(), LzmaOptions::DICT_SIZE_DEFAULT, None);
let mut decompressed = Vec::new();
reader.read_to_end(&mut decompressed).unwrap();
assert_eq!(&decompressed[..], b"Hello, world!");

Implementations

impl<R> Lzma2Reader<R>

pub fn into_inner(self) -> R

Unwraps the reader, returning the underlying reader.

pub fn inner(&self) -> &R

Returns a reference to the inner reader.

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

Returns a mutable reference to the inner reader.

impl<R: Read> Lzma2Reader<R>

pub fn new(inner: R, dict_size: u32, preset_dict: Option<&[u8]>) -> Self

Create a new LZMA2 reader. inner is the reader to read compressed data from. dict_size is the dictionary size in bytes.

Trait Implementations

impl<R: Read> Read for Lzma2Reader<R>

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.

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

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

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.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

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

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

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

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

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

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

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

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

Reads the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

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

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

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