Function std.string.lastIndexOfAny

Searches haystack for the last occurrence of any of the characters in needles.

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 needles in
needles characters to search for in haystack
stopIdx index in haystack to stop searching at (exclusive); defaults to haystack.length
cs specifies whether comparisons are case-sensitive (Yes.caseSensitive) or not (No.caseSensitive)

Returns

The index of the last occurrence of any of the characters of needles in haystack. If no character of needles is found or stopIdx is 0, then -1 is returned. If the parameters are not valid UTF, the result will still be in the range [-1 .. stopIdx], but will not be reliable otherwise.

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
