erase(
    xref:BloombergLP/bdlc/FlatHashSet/const_iterator.adoc[const_iterator] first,
    xref:BloombergLP/bdlc/FlatHashSet/const_iterator.adoc[const_iterator] last);
----

== Description

Remove from this set the elements starting at the specified `first` position up to, but not including, the specified `last` position, and return `last`. This method invalidates all iterators and references to the removed elements. The behavior is undefined unless `first` and `last` are valid iterators on this set, and the `first` position is at or before the `last` position in the iteration sequence provided by this container.

== Return Value

iterator equal to `last`

== Parameters
