clearremoves all elements from the set
countreturns the number of elements matching a certain key
emptytrue if the set has no elements
endreturns an iterator just past the last element of a set
equal_rangereturns iterators to the first and just past the last elements matching a specific key
eraseremoves elements from a set
findreturns an iterator to specific element
insertinsert items into a set
key_compreturns the function that compares keys
lower_boundreturns an iterator to the first element greater than or equal to a certain value
max_sizereturns the maximum number of elements that the set can hold
rbeginreturns a reverse_iterator to the end of the set
rendreturns a reverse_iterator to the beginning of the set
sizereturns the number of items in the set
