fn parse_typed(
model: &Model,
declared: ValueType,
text: &str,
) -> Result<Value, String>Expand description
Parse cell text as declared, the measure’s declared type. The declared
type WINS over the text’s shape: "42" for a Text measure is text, not a
number. Unparsable text is an error (never a coerced value), so a bad edit
leaves the prior typed cell untouched.
Dates and booleans reuse the formula grammar’s own literal forms (via
parser::parse_expr on #...# / TRUE|FALSE), so a date a formula
accepts is a date a cell accepts. Numbers use f64::from_str instead: the
formula tokenizer reads digits and . only, and a cell must accept -3.5
and 1e9.
