ptrdiff_t indexOf(Range)(Range s, dchar c, CaseSensitive cs = Yes.caseSensitive) if (isInputRange!Range && isSomeChar!(ElementType!Range) && !isSomeString!Range)Searches for a character in a string or range.
s | string or InputRange of characters to search for c in |
c | character to search for in s |
startIdx | index to a well-formed code point in s to start searching from; defaults to 0 |
cs | specifies whether comparisons are case-sensitive (Yes.caseSensitive) or not (No.caseSensitive). |
c is found in s, then the index of its first occurrence is
returned. If c is not found or startIdx is greater than or equal to s.length, then -1 is returned. If the parameters are not valid UTF, the result will still be either -1 or in the range startIdx /.html# s.length">startIdx .. s.length, but will not be reliable otherwise.
startIdx does not represent a well-formed
code point, then a UTFException may be thrown.
