[][src]Struct async_std::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 write bytes that are not valid UTF-8 will return an error.

Methods

impl Stdin[src]

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

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?;

pub async fn lock<'_>(&'_ self) -> StdinLock<'static>[src]

This is supported on unstable only.

Locks this handle to the standard input stream, returning a readable guard.

The lock is released when the returned lock goes out of scope. The returned guard also implements the Read trait for accessing the underlying data.

Examples

use async_std::io;
use async_std::prelude::*;

let mut buffer = String::new();

let stdin = io::stdin();
let mut handle = stdin.lock().await;

handle.read_to_string(&mut buffer).await?;
