Struct io_extras::raw::RawWriteable

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

A non-owning unsafe I/O handle that implements Write. Write functions considered are safe, so this type requires unsafe to construct.

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 AsRawHandleOrSocket for RawWriteable

RawWriteable doesn’t own its handle.

fn as_raw_handle_or_socket(&self) -> RawHandleOrSocket

Like AsRawHandle::as_raw_handle and AsRawSocket::as_raw_socket but can return either type.

impl Clone for RawWriteable

fn clone(&self) -> RawWriteable

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RawWriteable

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

Formats the value using the given formatter.

impl FromRawHandle for RawWriteable

RawWriteable doesn’t own its handle.

unsafe fn from_raw_handle(raw_handle: RawHandle) -> Self

Constructs a new I/O object from the specified raw handle.

impl FromRawHandleOrSocket for RawWriteable

RawWriteable doesn’t own its handle.

unsafe fn from_raw_handle_or_socket(
    raw_handle_or_socket: RawHandleOrSocket
) -> Self

Like FromRawHandle::from_raw_handle and FromRawSocket::from_raw_socket but can be passed either type.

impl IntoRawHandleOrSocket for RawWriteable

RawWriteable doesn’t own its handle.

fn into_raw_handle_or_socket(self) -> RawHandleOrSocket

Like IntoRawHandle::into_raw_handle and IntoRawSocket::into_raw_socket but can return either type.

impl Write for RawWriteable

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.
