pub fn from_numeric_text(raw: &str) -> Result<u64, NumericError>Expand description
Parse a numeric(20,0)::text result back into a counter.
Strict on purpose. A scale-0 column renders without a fractional part, so
anything else — 4.0, +4, 4, 4e2, NaN — means the value did not
come from where this function assumes, and guessing at it would be how a
silently wrong sequence enters the log.
