Struct utf8_io::Utf8Duplexer

pub struct Utf8Duplexer<Inner: HalfDuplex> { /* fields omitted */ }

An interactive UTF-8 stream, combining Utf8Reader and Utf8Writer.

Implementations

impl<Inner: HalfDuplex> Utf8Duplexer<Inner>

pub fn new(inner: Inner) -> Self

Construct a new instance of Utf8Duplexer wrapping inner.

pub fn into_inner(self) -> Result<Inner>

Flush any pending output and return the inner output stream.

Trait Implementations

impl<Inner: HalfDuplex + AsRawFd> AsRawFd for Utf8Duplexer<Inner>

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl<Inner: HalfDuplex + Debug> Debug for Utf8Duplexer<Inner>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Inner: HalfDuplex> Duplex for Utf8Duplexer<Inner>

impl<Inner: HalfDuplex> Read for Utf8Duplexer<Inner>

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_string(&mut self, buf: &mut String) -> Result<usize>

Read all bytes until EOF in this source, appending them to buf.

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, Global>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into 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<Inner: HalfDuplex> ReadStr for Utf8Duplexer<Inner>

fn read_str(&mut self, buf: &mut str) -> Result<usize>

Like read but produces the result in a str. Be sure to check the size field of the return value to see how many bytes were written.

fn read_exact_str(&mut self, buf: &mut str) -> Result<()>

Like read_exact but produces the result in a str.

impl<Inner: HalfDuplex> Write for Utf8Duplexer<Inner>

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.

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

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

pub fn is_write_vectored(&self) -> bool

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

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

pub fn write_all_vectored(
    &mut self,
    bufs: &mut [IoSlice<'_>]
) -> Result<(), Error>

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

Attempts to write multiple buffers into this writer.

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

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

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

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

impl<Inner: HalfDuplex> WriteStr for Utf8Duplexer<Inner>

fn write_str(&mut self, s: &str) -> Result<()>

Like Write::write_all, but takes a &str, allowing implementors which require valid UTF-8 to avoid re-validating the data.
