Implementations

impl PipeReader

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

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

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

Trait Implementations

impl AsFd for PipeReader

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

Borrows the file descriptor.

impl AsRawFd for PipeReader

fn as_raw_fd(&self) -> i32

Extracts the raw file descriptor.

impl Debug for PipeReader

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

Formats the value using the given formatter.

impl From<OwnedFd> for PipeReader

fn from(owned_fd: OwnedFd) -> PipeReader

Converts to this type from the input type.

impl From<PipeReader> for OwnedFd

fn from(pipe: PipeReader) -> OwnedFd

Converts to this type from the input type.

impl From<PipeReader> for Stdio

fn from(pipe: PipeReader) -> Stdio

Converts to this type from the input type.

impl FromRawFd for PipeReader

unsafe fn from_raw_fd(raw_fd: i32) -> PipeReader

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

impl IntoRawFd for PipeReader

fn into_raw_fd(self) -> i32

Consumes this object, returning the raw underlying file descriptor.

impl Read for &PipeReader

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

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.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Reads all bytes until EOF in this source, placing them into buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

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

Pull some bytes from this source into the specified buffer.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

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

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

Reads the exact number of bytes required to fill buf.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

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

Reads the exact number of bytes required to fill cursor.

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

where Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.

impl Read for PipeReader

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