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 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.
stopIdx size_t: 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 CaseSensitive: Indicates whether the comparisons are case sensitive.

Examples

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

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

import std.conv : to;

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

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