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

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

    pub struct StdoutLock<'a> { /* fields omitted */ }

A locked reference to the `Stdout` handle.

This handle implements the `Write` trait, and is constructed via the `Stdout::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 write bytes that are not valid UTF-8 will return an error.

## Trait Implementations
