Struct tee::TeeReader

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

An adapter for readers whose inputs are written to a tee(1)'d writer

Methods

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

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

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

Errors reported by the read will be interpreted as Errors for the read

Trait Implementations

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

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.
