:mrdocs:

Deduce the template parameters `KEY` and `VALUE` from the `value_type` of the iterators supplied to the constructor of `map`. Deduce the template parameter `COMPARATOR` from the other parameter passed to the constructor. This deduction guide does not participate unless the supplied allocator is convertible to `bsl::allocator<bsl::pair<const KEY, VALUE>>`.
