indexOfNeither

Returns the index of the first occurrence of any character not an elements in needles in haystack. If all element of haystack are element of needles -1 is returned.

Parameters

haystack const(Char)[]: String to search for needles in.
needles const(Char2)[]: Strings to search for in haystack.
startIdx size_t: slices haystack like this haystack[startIdx .. $]. If the startIdx is greater than or equal to the length of haystack the functions returns -1.
cs CaseSensitive: Indicates whether the comparisons are case sensitive.

Examples

assert(indexOfNeither("abba", "a", 2) == 2);
assert(indexOfNeither("def", "de", 1) == 2);
assert(indexOfNeither("dfefffg", "dfe", 4) == 6);

assert(indexOfNeither("def", "a") == 0);
