Implementations

impl PipeWriter

pub fn try_clone(&self) -> Result<PipeWriter, Error>

🔬This is a nightly-only experimental API. (anonymous_pipe #127154)

Create a new PipeWriter instance that shares the same underlying file description.

Trait Implementations

impl AsFd for PipeWriter

fn as_fd(&self) -> BorrowedFd<'_>

Borrows the file descriptor.

impl AsRawFd for PipeWriter

fn as_raw_fd(&self) -> i32

Extracts the raw file descriptor.

impl Debug for PipeWriter

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

Formats the value using the given formatter.

impl From<OwnedFd> for PipeWriter

fn from(owned_fd: OwnedFd) -> PipeWriter

Converts to this type from the input type.

impl From<PipeWriter> for OwnedFd

fn from(pipe: PipeWriter) -> OwnedFd

Converts to this type from the input type.

impl From<PipeWriter> for Stdio

fn from(pipe: PipeWriter) -> Stdio

Converts to this type from the input type.

impl FromRawFd for PipeWriter

unsafe fn from_raw_fd(raw_fd: i32) -> PipeWriter

Constructs a new instance of Self from the given raw file descriptor.

impl IntoRawFd for PipeWriter

fn into_raw_fd(self) -> i32

Consumes this object, returning the raw underlying file descriptor.

impl Write for &PipeWriter

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

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

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

Flushes 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 is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector #69941)

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

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

🔬This is a nightly-only experimental API. (write_all_vectored #70436)

Attempts to write multiple buffers 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

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
