int rawIndex
read / write

Returns the starting position of the current rune in the string.

Returns null if the current rune is null. /

/** Resets the iterator to the rune at the specified index of the string.

Setting a negative rawIndex, or one greater than or equal to string.length, is an error. So is setting it in the middle of a surrogate pair.

Setting the position to the end of then string will set current to null.
