Struct compress::flate::Decoder

pub struct Decoder<R> {
    pub r: R,
    // some fields omitted
}

The structure that is used to decode an LZ4 data stream. This wraps an internal reader which is used as the source of all data.

Fields

r: R

Wrapped reader which is exposed to allow getting it back.

Implementations

impl<R: Read> Decoder<R>

pub fn new(r: R) -> Decoder<R>

Creates a new flate decoder which will read data from the specified source

pub fn eof(&self) -> bool

Returns whether this deflate stream has reached the EOF marker

pub fn reset(&mut self)

Resets this flate decoder. Note that this could corrupt an in-progress decoding of a stream.

Trait Implementations

impl<R: Read> Read for Decoder<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.

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.

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, appending them to 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 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.
