Struct lzma::Reader

pub struct Reader<R: Read> { /* fields omitted */ }

A LZMA stream reader.

Methods

impl<R: Read> Reader<R>

fn new(stream: R, properties: Properties) -> Result<Reader<R>, Error>

Creates a LZMA reader with the given model properties and the given stream.

fn from(stream: R) -> Result<Reader<R>, Error>

Creates a LZMA stream from the given stream, reading the model properties.

fn properties(&self) -> &Properties

Returns the model properties.

fn cached(&self) -> usize

Returns the size of the internal cache.

fn into_inner(self) -> R

Unwraps this Reader, returning the underlying reader.

Note that any leftover data in the internal buffer is lost.

unsafe fn inner(&mut self) -> &mut R

Returns the inner stream mutably.

Note that reading bytes from the raw stream might corrupt the decoding.

unsafe fn set_uncompressed(&mut self, value: Option<u64>)

Sets the uncompressed size.

Note that changing the uncompressed size might corrupt the decoding.

unsafe fn reset(&mut self, properties: Option<Properties>)

Resets the decoder.

Note that resetting might corrupt the decoding.

fn decode<W: Write>(&mut self, writer: W) -> Result<usize, Error>

Decode one unit and return the decoded amount.

Note the writer should not do partial writes, or some of the decoded data will be lost.

Trait Implementations

impl<R: Debug + Read> Debug for Reader<R>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<R: Read> Read for Reader<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_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

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

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

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

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

Read the exact number of bytes required to fill buf.

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

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

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

the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

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

Creates an adaptor which will chain this stream with another.

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

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