    fn template(&self, name: &MetricName, _kind: InputKind) -> LineTemplate {
        LineTemplate::new(vec![
            LineOp::Literal(format!("{} ", name.join(".")).to_uppercase().into()),
            LineOp::ValueAsText,
            LineOp::Literal(" ".into()),
            LineOp::LabelExists(
                "abc".into(),
                vec![
                    LabelOp::LabelKey,
                    LabelOp::Literal(":".into()),
                    LabelOp::LabelValue,
                ],
            ),
            LineOp::NewLine,
        ])
    }

pub fn print<L>( &self, output: &mut dyn Write, value: MetricValue, lookup: L, ) -> Result<()>

where L: Fn(&str) -> Option<Arc<String>>,

Template execution applies commands in turn, writing to the output.
