lastIndexOfNeither

ptrdiff_t lastIndexOfNeither(Char, Char2)(const(Char)[]  haystack,
         const(Char2)[]  needles,  in  CaseSensitive cs =  Yes.caseSensitive) if (isSomeChar!Char &&  isSomeChar!Char2)

@safe pure

Searches for the last character in haystack that is not in needles.

Parameters

`haystack`	string to search for needles in
`needles`	characters to search for in `haystack`
`stopIdx`	index in `haystack` to stop searching at (exclusive); defaults to `haystack.length`
`cs`	specifies whether comparisons are case-sensitive (`Yes.caseSensitive`) or not (`No.caseSensitive`)

Returns

The index of the last character in haystack that is not an element of

needles. If all characters of haystack are in needles or stopIdx is 0, then -1 is returned. If the parameters are not valid UTF, the result will still be in the range stopIdx">-1 .. stopIdx, but will not be reliable otherwise.
