pub fn unsupported_quantity(line: &str) -> Option<String>Expand description
The quantity in line that states something about token economics, if there is one: a
number followed by %, ％, percent, per cent, percentage points or pp, or a
multiplier (3x, 3 × cheaper, 2 times fewer), in a sentence that also uses a plain
word of the economics vocabulary; or a multiplier or fraction word (half, twice,
a third) in a sentence that also says something went down. This reads one line as it
stands; prose_quantities reads a whole file, with wrapped sentences joined.
