| struct | std::_Rb_tree_merge_helper |
A standard container made up of unique keys, which can be retrieved in logarithmic time.
| _Key | Type of key objects. |
| _Compare | Comparison function object type, defaults to less<_Key>. |
| _Alloc | Allocator type, defaults to allocator<_Key>. |
Meets the requirements of a container, a reversible container, and an associative container (using unique keys).
Sets support bidirectional iterators.
The private tree data is declared exactly the same way for set and multiset; the distinction is made entirely in how the tree functions are called (*_unique versus *_equal, same as the standard).

Builds a set from a range.
| __first | An input iterator. |

Create a set consisting of copies of the elements from [__first,__last). This is linear in N if the range is already sorted, and NlogN otherwise (where N is distance(__first,__last)).

Create a set consisting of copies of the elements from [__first,__last). This is linear in N if the range is already sorted, and NlogN otherwise (where N is distance(__first,__last)).

Set copy constructor.
Whether the allocator is copied depends on the allocator traits.

Set move constructor
The newly-created set contains the exact contents of the moved instance. The moved instance is a valid, but unspecified, set.

| __l | An initializer_list. |
| __comp | A comparison functor. |
| __a | An allocator object. |
Create a set consisting of copies of the elements in the list. This is linear in N if the list is already sorted, and NlogN otherwise (where N is __l.size()).

Attempts to build and insert an element into the set.
| __args | Arguments used to generate an element. |
This function attempts to build and insert an element into the set. A set relies on unique keys and thus an element is only inserted if it is not already present in the set.
Insertion requires logarithmic time.
|
inline |
Attempts to insert an element into the set.
| __pos | An iterator that serves as a hint as to where the element should be inserted. |
| __args | Arguments used to generate the element to be inserted. |
This function is not concerned about whether the insertion took place, and thus does not return a boolean like the single-argument emplace() does. Note that the first parameter is only a hint and can potentially improve the performance of the insertion process. A bad hint would cause no gains in efficiency.
For more on hinting, see: https://gcc.gnu.org/onlinedocs/libstdc++/manual/associative.html#containers.associative.insert_hints
Insertion requires logarithmic time (if the hint is not taken).

Returns a read-only (constant) iterator that points one past the last element in the set. Iteration is done in ascending order according to the keys.

Finds a subsequence matching given key.

Erases elements according to the provided key.

This function erases all the elements located by the given key from a set. Note that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

inline |
Erases a [__first,__last) range of elements from a set.
| __first | Iterator pointing to the start of the range to be erased. |
| __last | Iterator pointing to the end of the range to be erased. |
This function erases a sequence of elements from a set. Note that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

Erases an element from a set.
| __position | An iterator pointing to the element to be erased. |
This function erases an element, pointed to by the given iterator, from a set. Note that this function only erases the element, and that if the element is itself a pointer, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

This function takes a key and tries to locate the element with which the key matches. If successful the function returns an iterator pointing to the sought after element. If unsuccessful it returns the past-the-end ( end() ) iterator.

Swaps data with another set.
| __x | A set of the same element and allocator types. |
This exchanges the elements between two sets in constant time. (It is only swapping a pointer, an integer, and an instance of the Compare type (which itself is often stateless and empty), so it should be quite fast.) Note that the global std::swap() function is specialized such that std::swap(s1,s2) will feed to this function.
Whether the allocators are swapped depends on the allocator traits.
