These deduction guides are provided for to allow deduction from:
1) A key-container, a mapped-container and a comparator.
2) A key-container, a mapped-container and an allocator.
3) A key-container, a mapped-container, a comparator and an allocator.
4) The
std::sorted_equivalent_t tag, a key-container, a mapped-container and a comparator.
5) The
std::sorted_equivalent_t tag, a key-container, a mapped-container and an allocator.
6) The
std::sorted_equivalent_t tag, a key-container, a mapped-container, a comparator and an allocator.
7) An iterator range and a comparator.
8) The
std::sorted_equivalent_t tag, an iterator range and a comparator.
11) The
std::initializer_list and a comparator.These overloads participate in overload resolution only if InputIt satisfies LegacyInputIterator, Alloc satisfies Allocator, and Comp does not satisfy Allocator.
Note: the extent to which the library determines that a type does not satisfy LegacyInputIterator is unspecified, except that as a minimum integral types do not qualify as input iterators. Likewise, the extent to which it determines that a type does not satisfy Allocator is unspecified, except that as a minimum the member type Alloc::value_type must exist and the expression std::declval<Alloc&>().allocate(std::size_t{}) must be well-formed when treated as an unevaluated operand.
