lastIndexOf

ptrdiff_t lastIndexOf(Char)(const(Char)[]  s,  in  dchar  c,
         in  CaseSensitive cs =  Yes.caseSensitive) if (isSomeChar!Char)

@safe pure

Searches for the last occurrence of a character in a string.

Parameters

`s`	string to search for `c` in
`c`	character to search for in `s`
`startIdx`	index of 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`)

Returns

If c is found in s, then the index of its last 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 .. s.length], but will not be reliable otherwise.

Throws

If the sequence ending at startIdx does not represent a well-formed

code point, then a UTFException may be thrown.

ptrdiff_t lastIndexOf(Char1,  Char2)(const(Char1)[]  s,  const(Char2)[]  sub,
         in  CaseSensitive cs =  Yes.caseSensitive) if (isSomeChar!Char1 &&  isSomeChar!Char2)

@safe pure

Searches for the last occurrence of a substring in a string.

Parameters

`s`	string to search for `sub` in
`sub`	substring 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`)

Returns

The index of the last occurrence of sub in s. If sub 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 .. s.length], but will not be reliable otherwise.

Throws

If the sequence starting at startIdx does not represent a well-formed

code point, then a UTFException may be thrown.

Bugs

Does not work with case-insensitive strings where the mapping of toLower and toUpper is not 1:1.
