Struct tee_readwrite::TeeWriter

pub struct TeeWriter<L, R> { /* fields omitted */ }

Mirror all writes to a std::io::Write to another std::io::Write

This is useful if you want to log all writes from a Writeer to some file (the Writer)

Methods

impl<L, R> TeeWriter<L, R>

pub fn new(write: L, output: R) -> Self

Create a new TeeWriter from two Write impls.

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

Moves the wrapped Read and Write out

pub fn borrow_output(&self) -> &R

Borrows the output type

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

Borrows the output type mutably

Trait Implementations

impl<L: Write, R: Write> Write for TeeWriter<L, R>

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

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

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

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

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

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