Function std.string.lastIndexOfNeither
Returns the last index of the first occurence of any character that is not
an elements in needles
in haystack
. If all element of
haystack
are element of needles
-1
is returned.
ptrdiff_t lastIndexOfNeither(Char, Char2)
(
const(Char)[] haystack,
const(Char2)[] needles,
in CaseSensitive cs = Yes .caseSensitive
) pure @safe
if (isSomeChar!Char && isSomeChar!Char2);
ptrdiff_t lastIndexOfNeither(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
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 equal the length of haystack the functions
returns -1 . |
cs | Indicates whether the comparisons are case sensitive. |
Example
writeln(lastIndexOfNeither("abba", "a")); // 2
writeln(lastIndexOfNeither("def", "f")); // 1
Example
