Struct BorrowedWriteable

pub struct BorrowedWriteable<'a> { /* private fields */ }

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.

Implementations

impl<'a> BorrowedWriteable<'a>

pub fn borrow(grip: BorrowedGrip<'a>) -> Self

Create a BorrowedReadable that can write to a BorrowedGrip.

Trait Implementations

impl<'a> AsFd for BorrowedWriteable<'a>

BorrowedWriteable borrows its handle.

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

Borrows the file descriptor.

impl<'a> Debug for BorrowedWriteable<'a>

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

Formats the value using the given formatter.

impl<'a> Write for BorrowedWriteable<'a>

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

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

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

Flushes 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

where Self: Sized,

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