Struct unsafe_io::UnsafeWriteable

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

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

Like UnsafeHandle, 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 AsRawFd for UnsafeWriteable

UnsafeWriteable doesn't own its handle; see the comments for impl AsRawFd for UnsafeHandle.

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Clone for UnsafeWriteable

fn clone(&self) -> UnsafeWriteable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for UnsafeWriteable

impl Debug for UnsafeWriteable

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

Formats the value using the given formatter.

impl FromRawFd for UnsafeWriteable

UnsafeWriteable doesn't own its handle; see the comments for impl AsRawFd for UnsafeHandle.

unsafe fn from_raw_fd(raw_fd: RawFd) -> Self

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

impl FromUnsafeHandle for UnsafeWriteable

UnsafeWriteable doesn't own its handle; see the comments for impl AsRawFd for UnsafeHandle.

unsafe fn from_unsafe_handle(unsafe_handle: UnsafeHandle) -> Self

Constructs a new instance of Self from the given unsafe handle.

impl IntoRawFd for UnsafeWriteable

UnsafeWriteable doesn't own its handle; see the comments for impl AsRawFd for UnsafeHandle.

fn into_raw_fd(self) -> RawFd

Consumes this object, returning the raw underlying file descriptor.

impl Write for UnsafeWriteable

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.

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

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