C++ seterase()function is used to remove either a single element associated with given key or a range of elements ([first, last)) from the set container. Hence, the size will be reduced by the number of elements removed. Syntax voiderase (iterator position);//until C++ 11 size_type era...

Probably comes down to the fast path using _Unchecked_erase which has an implicit requirement that the values are all still valid as it callsbucketto hash values. STL/stl/inc/xhash Line 1036 in2f03bdf const size_type _Bucket = bucket(_Traits::_Kfn(_Eraser._Next->_Myval)); // throw...
Compared to aSmallVectorthat would never grow,FixedCapacityVectorwill be slightly more efficient (less checks) and make the intent clear, with nice additional iterator validity properties (begin()is never invalidated, iterators before any insert / erase are never invalidated). In addition, if type ...
