Method flush

src/io/streams.rs:307–320

Asyncronously flush the output stream. Initiates a flush, and then awaits until the flush is complete and the output stream is ready for writing again. This method is the same as [`AsyncWrite::flush`], but doesn't require a `&mut self`. Fails with a `std::io::Error` indicating either an error returned by the stream flush, using the debug string provided by the WASI error, or else that the stream

(&self)

    /// or else that the stream is closed, indicated by
    /// `std::io::ErrorKind::ConnectionReset`.
    pub async fn flush(&self) -> std::io::Result<()> {
        match self.stream.flush() {
            Ok(()) => {
                self.ready().await;
                Ok(())
            }
            Err(StreamError::Closed) => {
                Err(std::io::Error::from(std::io::ErrorKind::ConnectionReset))
            }
