Function std.string.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 UTFException may be thrown.

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

ptrdiff_t indexOfAny(Char, Char2) (
  const(Char)[] haystack,
  const(Char2)[] needles,
  in size_t startIdx,
  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.
startIdx slices haystack like this haystack[startIdx .. $]. If the startIdx is greater than or equal to the length of haystack the functions returns -1.
cs Indicates whether the comparisons are case sensitive.

Example

import std.conv : to;

ptrdiff_t i = "helloWorld".indexOfAny("Wr");
writeln(i); // 5
i = "öällo world".indexOfAny("lo ");
writeln(i); // 4

Example

import std.conv : to;

ptrdiff_t i = "helloWorld".indexOfAny("Wr", 4);
writeln(i); // 5

i = "Foo öällo world".indexOfAny("lh", 3);
writeln(i); // 8
