Struct async_std::io::Stdin

pub struct Stdin(_);

A handle to the standard input of the current process.

Created by the stdin function.

This type is an async version of std::io::Stdin.

Methods

impl Stdin

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

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) -> RawFd

This is supported on Unix only.

Extracts the raw file descriptor.

impl AsRawHandle for Stdin

fn as_raw_handle(&self) -> RawHandle

This is supported on Windows only.

Extracts the raw handle, without taking any ownership.

impl Debug for Stdin

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

Formats the value using the given formatter.

impl AsyncRead for Stdin

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

Attempt to read from the AsyncRead into buf.

unsafe fn initializer(&self) -> Initializer

Determines if this AsyncReader can work with buffers of uninitialized memory.

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.
