Enum PrintStream 

pub enum PrintStream {
    Stdout,
    Stderr,
}

Identifies the output stream for a single print fragment.

Today the print() builtin only writes to Stdout. The Stderr variant is included for forward compatibility with a future print(..., file=sys.stderr) implementation so the collected-output API shape does not have to change when that lands.

Variants

Stdout

Standard output — the default for every print() call today.

Stderr

Standard error — reserved for future print(..., file=sys.stderr) support.
