Struct fluvio_future::io::Stdin

pub struct Stdin(_);

A handle to the standard input of the current process.

This reader is created by the stdin function. See its documentation for more.

Note: Windows Portability Consideration

When operating in a console, the Windows implementation of this stream does not support non-UTF-8 byte sequences. Attempting to read bytes that are not valid UTF-8 will return an error.

Implementations

impl Stdin

pub async fn read_line(&self, buf: &mut String) -> Result<usize, Error>

Reads a line of input into the specified buffer.

Examples

use async_std::io;

let stdin = io::stdin();
let mut line = String::new();
stdin.read_line(&mut line).await?;

Trait Implementations

impl AsRawFd for Stdin

fn as_raw_fd(&self) -> i32

Extracts the raw file descriptor.

impl AsyncRead for Stdin

fn poll_read(
    self: Pin<&mut Stdin>,
    cx: &mut Context<'_>,
    buf: &mut [u8]
) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    bufs: &mut [IoSliceMut<'_>]
) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl Debug for Stdin

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

Formats the value using the given formatter.
