The obvious answer is no, since there is no function in the
interface which supports this. There is also no way to get to
an iterator
from a local_iterator
, for the obvious reason
that a local_iterator
contains a lot less information. (For
most implementations, I suspect that it would be fairly simple
to implement erase( local_iterator )
, had the standard
required it. On the other hand, I can't think of a conceivable
use for it, which may be why the standard didn't require it.)
Is it possible to remove elements from an std::unordered_set through bucket iterators?

Like the question says, can you remove an element from a std::unordered_set
using a bucket iterator (local_iterator
)? I can see two possible solutions:
- Since erase() does only accept global
iterator
s, is there equivalent functionality forlocal_iterator
? - Is it possible to obtain the equivalent global
iterator
for alocal_iterator
?
If it's not feasible, please elaborate on why it's not.
