Create a `Json` object having the type `bsl::string` and the same value as the specified `string` by moving (in constant time) the contents of `string` to the new `Json` object. Optionally specify the `basicAllocator` used to supply memory. If `basicAllocator` is not specified, the allocator associated with `string` is propagated for use in the newly‐created `Json` object. `string` is left in a valid but unspecified state. This function does not participate in overload resolution unless the specified `t_STRING_TYPE` is `bsl::string`. The behavior is undefined unless `string` is valid UTF‐8 (see `bdlde::Utf8Util::isValid`).
