# 1.0.0[−][src]Struct std::io::Stdout

    pub struct Stdout { /* fields omitted */ }

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.

### Important traits for StdoutLock<'a>

`impl<'a> Write for StdoutLock<'a>`

`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(b"hello world")?;

        Ok(())
    }Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
