:relfileprefix: ../../../
:mrdocs:

Return, by value, a datum having the copy of the specified `StringRef` `value`, using the specified `allocator` to supply memory (if needed). The behavior is undefined unless `value.length() <= UINT_MAX`. Note that the copied string is owned, and will be freed if `Datum::destroy` is called on the returned object.
