pub struct Stdout(/* private fields */);
Expand description
A handle to the standard output of the current process.
This writer is created by the stdout
function. See its documentation
for more.
Note: Windows Portability Consideration
When operating in a console, the Windows implementation of this stream does not support non-UTF-8 byte sequences. Attempting to write bytes that are not valid UTF-8 will return an error.
