Struct std::io::StdinLock1.0.0[][src]

pub struct StdinLock<'a> { /* fields omitted */ }
Expand description

A locked reference to the Stdin handle.

This handle implements both the Read and BufRead traits, and is constructed via the Stdin::lock method.

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.

Examples

use std::io::{self, Read};

fn main() -> io::Result<()> {
    let mut buffer = String::new();
    let stdin = io::stdin(); // We get `Stdin` here.
    {
        let mut handle = stdin.lock(); // We get `StdinLock` here.
        handle.read_to_string(&mut buffer)?;
    } // `StdinLock` is dropped here.
    Ok(())
}
Run

Returns the contents of the internal buffer, filling it with more data from the inner reader if it is empty. Read more
