Implementations

impl Output

pub fn new(io_arg: IoArg) -> Result<Self>

Either calls stdout or File::create depending on io_arg.

pub fn into_write(self) -> Box<dyn Write>

Wraps either standard out or the file in a Box<dyn Write>. In case of Output::StdOut standard out will be locked. In case of Output::File the file will be wrapped in std::io::BufWriter in order to minimize system calls.
