:mrdocs:

Create a `function` by moving the target from the specified `original`.

== Synopsis

Declared in `<bslstl_function.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
function(xref:BloombergLP/bslmf/MovableRef.adoc[BloombergLP::bslmf::MovableRef<function>] original) noexcept;
----

== Description

Create a `function` having the same target as the specified `original` object. Use `original.get_allocator()` as the allocator to supply memory. The `original` object is set to empty after the new object is created. If the target qualifies for the small‐object optimization (see class‐level documentation), then it is move‐constructed into the new object; otherwise ownership of the target is transferred without using the target's move constructor.

== Parameters
