Function `std.string.lastIndexOfAny`

Returns the index of the last occurrence of any of the elements in needles in haystack. If no element of needles is found, then -1 is returned. The stopIdx slices haystack in the following way s[0 .. stopIdx]. stopIdx represents a codeunit index in haystack. If the sequence ending at startIdx does not represent a well formed codepoint, then a UTFException may be thrown.

				  in CaseSensitive cs = Yes.caseSensitive

				  const(Char)[] haystack,
				

				  const(Char2)[] needles,

Parameters

Name	Description
haystack	String to search for needles in.
needles	Strings to search for in haystack.
stopIdx	slices haystack like this `haystack[0 .. stopIdx]`. If the stopIdx is greater than or equal to the length of haystack the functions returns `-1`.
cs	Indicates whether the comparisons are case sensitive.

Example

ptrdiff_t i = "helloWorld".lastIndexOfAny("Wlo");
writeln(i); // 8

i = "Foo öäöllo world".lastIndexOfAny("öF");
writeln(i); // 8

Example

import std.conv : to;

ptrdiff_t i = "helloWorld".lastIndexOfAny("Wlo", 4);
writeln(i); // 3

i = "Foo öäöllo world".lastIndexOfAny("öF", 3);
writeln(i); // 0
