indexOfAny

Returns the index of the first occurrence of any of the elements in needles in haystack. If no element of needles is found, then -1 is returned. The startIdx slices haystack in the following way haystack[startIdx .. $]. startIdx represents a codeunit index in haystack. If the sequence ending at startIdx does not represent a well formed codepoint, then a std.utf.UTFException may be thrown.

Parameters

haystack const(Char)[]: String to search for needles in.
needles const(Char2)[]: Strings to search for in haystack.
cs CaseSensitive: Indicates whether the comparisons are case sensitive.

ptrdiff_t i = "helloWorld".indexOfAny("Wr");
assert(i == 5);
i = "öällo world".indexOfAny("lo ");
