pub fn stderr() -> Stderr ⓘExpand description
Return a handle to inherited standard error.
Every call returns a cheap Copy handle referencing the same process-wide
stderr state. Writes are unbuffered and serialized through this module’s
stderr lock.
§Returns
A Stderr handle.
§Errors and panics
This function does not fail or intentionally panic. I/O errors are reported
by the handle’s Write implementation.
