Struct tokio_fs::Stderr

source · [−]

pub struct Stderr { /* private fields */ }

Expand description

A handle to the standard error stream of a process.

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

Created by the stderr function.
