Create an unordered multiset by moving from `original`.

== Synopsis

Declared in `<bslstl_unorderedmultiset.h>`

unordered_multiset(xref:BloombergLP/bslmf/MovableRef.adoc[BloombergLP::bslmf::MovableRef<unordered_multiset>] original);
----

== Description

Create an unordered multiset having the same value as the specified `original` object by moving (in constant time) the contents of `original` to the new unordered multiset. Use a copy of `original.hash_function()` to generate hash values for the keys contained in this unordered multiset. Use a copy of `original.key_eq()` to verify that two keys are equivalent. The allocator associated with `original` is propagated for use in the newly‐created unordered multiset. `original` is left in a valid but unspecified state.

== Parameters
