Struct tees::TeeReader

pub struct TeeReader<R: Read, W: Write> { /* fields omitted */ }

An adapter for readers whose inputs are written to a "tee"'d writer

Implementations

impl<R: Read, W: Write> TeeReader<R, W>

pub fn new(reader: R, writer: W) -> TeeReader<R, W>

Returns a TeeReader which can be used as Read whose reads delegate bytes read to the provided reader and write to the provided writer. The write operation must complete before the read completes.

Errors reported by the write operation will be interpreted as errors for the read

pub fn into_inner(self) -> (R, W)

Consumes the TeeReader, returning the wrapped reader and writer.

Trait Implementations

impl<R: Read, W: Write> Read for TeeReader<R, W>

pub 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>) -> 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.

impl<R: Read + Seek, W: Write + Seek> Seek for TeeReader<R, W>

pub fn seek(&mut self, pos: SeekFrom) -> Result<u64>

Seek to an offset, in bytes, in a stream.

pub fn stream_len(&mut self) -> Result<u64, Error>

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

Returns the length of this stream (in bytes).

pub fn stream_position(&mut self) -> Result<u64, Error>

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

Returns the current seek position from the start of the stream.
