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.

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

ptrdiff_t lastIndexOfAny(Char, Char2) (
  const(Char)[] haystack,
  const(Char2)[] needles,
  in size_t stopIdx,
  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.
stopIdx slices haystack like this haystack[0 .. stopIdx]. If the stopIdx is greater equal 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
