Struct Stderr 

pub struct Stderr { /* private fields */ }

Indirection for standard error.

Depending on mode, messages are immediately printed to standard error, or buffered in an internal buffer.

An optional progress string can be used to report temporary progress indication to the user. It’s always printed as the last lines of the standard error. When the standard error is created with WriteMode::Buffered, the progress is not saved in the internal buffer.
