std::io::Stdout - Rust
Description: API documentation for the Rust `Stdout` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, Stdout

# Struct std::io::Stdout 1.0.0 [−] [src]

    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.

## Methods

### `impl Stdout`
[src]

#### `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};

    let stdout = io::stdout();
    let mut handle = stdout.lock();

    handle.write(b"hello world")?;
    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`)
