Function std.string.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.

ptrdiff_t indexOfNeither(Char, Char2) (
  const(Char)[] haystack,
  const(Char2)[] needles,
  in CaseSensitive cs = Yes.caseSensitive
) pure @safe
if (isSomeChar!Char && isSomeChar!Char2);

ptrdiff_t indexOfNeither(Char, Char2) (
  const(Char)[] haystack,
  const(Char2)[] needles,
  in size_t startIdx,
  in CaseSensitive cs = Yes.caseSensitive
) pure @safe
if (isSomeChar!Char && isSomeChar!Char2);

Parameters

NameDescription
haystack String to search for needles in.
needles Strings to search for in haystack.
startIdx slices haystack like this haystack[startIdx .. $]. If the startIdx is greater equal the length of haystack the functions returns -1.
cs Indicates whether the comparisons are case sensitive.

Example

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

Example

writeln(indexOfNeither("def", "a")); // 0
writeln(indexOfNeither("def", "de")); // 2
