Reads values from text as format describes. Returns whether the whole text matched, and the values
read, as Anys.
scan :: (format: string, text: string) -> (bool, [] Any)Bytes of format must appear in the text as they are. %d and %i read a whole number (an s64),
%f a float, %b true or false, and %s a string in double quotes, returned without the
quotes. A %% matches and consumes a literal % and produces no value.
On a mismatch the result is false and the values read so far are returned. The values and the
array are allocated in temporary storage, so they are only valid until it is reset. Nothing is
freed by the caller.
Parameters
- format: string
- text: string
Returns
- bool
- [] Any
