Struct io_pipe::Writer

pub struct Writer { /* private fields */ }

Multi writer

You can clone this writer to write bytes from different threads.

All write calls will be executed immediately without blocking thread. It’s safe to use this writer inside async operations.

Example

use std::io::Write;

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

Write method will return an error, when reader dropped.

use std::io::Write;

let (mut writer, reader) = io_pipe::pipe();
drop(reader);
assert!(writer.write("hello".as_bytes()).is_err());

Trait Implementations

impl Clone for Writer

fn clone(&self) -> Writer

Returns a copy 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 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, fmt: 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.
