Struct readwrite::ReadWrite

pub struct ReadWrite<R: Read, W: Write>(pub R, pub W);

Combined reader and writer

Methods

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

pub fn new(r: R, w: W) -> Self

Bundle separate reader and writer into a combined pseudo-socket

pub fn borrow(&self) -> (&R, &W)

Borrow inner objects

pub fn borrow_read(&self) -> &R

Borrow the reader

pub fn borrow_write(&self) -> &W

Borrow the writer

pub fn borrow_mut(&mut self) -> (&mut R, &mut W)

Mutably borrow inner objects

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

Mutably borrow the reader

pub fn borrow_mut_write(&mut self) -> &mut W

Mutably borrow the writer

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

Convert ReadWrite back into individual reader and writer pair

pub fn into_reader(self) -> R

Convert ReadWrite back into the reader, dropping the writer

pub fn into_writer(self) -> W

Convert ReadWrite back into the writer, dropping the reader

Trait Implementations

impl<R: Read, W: Write> From<(R, W)> for ReadWrite<R, W>

fn from((r, w): (R, W)) -> Self

Performs the conversion.

impl<R: Read, W: Write> Read for ReadWrite<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.

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 chars(self) -> Chars<Self>

Deprecated since 1.27.0

: Use str::from_utf8 instead: https://doc.rust-lang.org/nightly/std/str/struct.Utf8Error.html#examples

🔬 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 [char]s.

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.

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

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

Write a buffer into this object, 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_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this write.

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.
