Struct tokio::io::Stdout

source · [−]

pub struct Stdout { /* private fields */ }

Expand description

A handle to the standard output stream of a process.

The handle implements the AsyncWrite trait, but beware that concurrent writes to Stdout must be executed with care.

Created by the stdout function.
