pub struct StandardStreamLock<'a> { /* private fields */ }
Expand description

StandardStreamLock is a locked reference to a StandardStream.

This implements the io::Write and WriteColor traits, and is constructed via the Write::lock method.

The lifetime 'a refers to the lifetime of the corresponding StandardStream.
