Reads values from text as format describes, storing them through the pointers in args.
Returns whether the whole text matched.
scan2 :: (text: string, format: string, args: ..Any) -> boolThe directives are those of scan. Each
directive stores into the next argument, which must be a pointer to a number, a bool or a string.
A number that does not fit the target (a 256 into a u8) makes the call fail, as does a missing
or null argument. On failure the targets read before the mismatch keep their new values and the
others are not touched. A string result points into text.
Floats read into a float or a float64, and a literal percent sign is written %%:
Parameters
- text: string
- format: string
- args: ..Any
Returns
- bool
