pub(crate) fn display_expression<F: AcirField>(
    expr: &Expression<F>,
    as_equal_to_zero: bool,
    return_values: Option<&PublicInputs>,
    f: &mut Formatter<'_>,
) -> ResultExpand description
Displays an expression as a quadratic polynomial.
If as_equal_to_zero is true, the expression is displayed as equaling zero,
where it’s tried to shown as a polynomial equal to the largest witness, if possible.
If the optional return_values is provided, the expression is displayed preferring to show
ASSERT return_value = ... when possible.
