1.0.0[−][src]Struct std::io::Stdout
A handle to the global standard output stream of the current process.
Each handle shares a global buffer of data to be written to the standard
output stream. Access is also synchronized via a lock and explicit control
over locking is available via the lock
method.
Created by the io::stdout
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 write bytes that are not valid UTF-8 will return an error.
Methods
impl Stdout
[src]
ⓘImportant traits for StdoutLock<'_>pub fn lock(&self) -> StdoutLock
[src]
Locks this handle to the standard output stream, returning a writable guard.
The lock is released when the returned lock goes out of scope. The
returned guard also implements the Write
trait for writing data.
Examples
use std::io::{self, Write}; fn main() -> io::Result<()> { let stdout = io::stdout(); let mut handle = stdout.lock(); handle.write_all(b"hello world")?; Ok(()) }Run
