Struct Writer 

pub struct Writer<B>(/* private fields */);

Adapts an IoBufMut to implement the std::io::Write trait.

This can be constructed with IoBufMut::into_writer

Implementations

impl<B> Writer<B>

pub fn new(buf: B) -> Self

Creates a new Writer from the given buffer.

pub fn as_inner(&self) -> &B

Returns a reference to the inner buffer.

pub fn as_inner_mut(&mut self) -> &mut B

Returns a mutable reference to the inner buffer.

Trait Implementations

impl<B> IntoInner for Writer<B>

type Inner = B

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<B: IoBufMut> Write for Writer<B>

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, Error>

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<(), Error>

Attempts to write an entire buffer into this writer.

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

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

Attempts to write multiple buffers into this writer.

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

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.
