Struct io_extras::owned::OwnedWriteable

#[repr(transparent)]
pub struct OwnedWriteable(_);

An owning I/O handle that implements Write.

This doesn’t implement Into* or From* traits.

Platform-specific behavior

On Posix-ish platforms, this writes to the handle as if it were a [File]. On Windows, this writes to a file-like handle as if it were a [File], and to a socket-like handle as if it were a TcpStream.

Trait Implementations

impl AsFd for OwnedWriteable

OwnedWriteable owns its handle.

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

Borrows the file descriptor.

impl Debug for OwnedWriteable

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

Formats the value using the given formatter.

impl Drop for OwnedWriteable

fn drop(&mut self)

Executes the destructor for this type.

impl FromFd for OwnedWriteable

OwnedWriteable owns its handle.

fn from_fd(fd: OwnedFd) -> Self

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

fn from_into_fd<Owned>(into_owned: Owned) -> Self where
    Owned: IntoFd, 

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

impl IntoFd for OwnedWriteable

OwnedWriteable owns its handle.

fn into_fd(self) -> OwnedFd

Consumes this object, returning the underlying file descriptor.

impl Write for OwnedWriteable

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>

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)

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

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

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

Attempts to write multiple buffers into this writer.

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

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

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

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