BloombergLP::ball::CategoryManager_RadixTree::operator=

Assign to this object the value of the specified rhs object, and return a reference providing modifiable access to this object. The contents of rhs are moved (in amortized constant time) to this object if get_allocator() == rhs.get_allocator(); otherwise, all elements in this object are either destroyed or move‐assigned to, and each additional element in rhs is move‐inserted into this object. rhs is left in a valid but unspecified state.
