Struct Writer

pub struct Writer { /* private fields */ }

A synchronous writer that implements Write.

This struct allows writing data synchronously, which can be read from a corresponding Reader. Multiple Writer instances can be created by cloning, allowing writes from different threads.

Notes

• All write calls are executed immediately without blocking the thread.
• It’s safe to use this writer inside async operations.
• Write method will return an error when the reader is dropped.

Example

use std::io::Write;
use io_pipe::pipe;

let (mut writer, reader) = pipe();
writer.write_all("hello".as_bytes()).unwrap();

Trait Implementations

impl Clone for Writer

fn clone(&self) -> Writer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Writer

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

Formats the value using the given formatter.

impl Write for Writer

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

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

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> IOResult<usize>

Like write, except that it writes from a slice of buffers.

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

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Attempts to write an entire buffer into this writer.

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

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

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

where Self: Sized,

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