-----------------------------------

             Summary: [C++] Create Buffer implementation that takes ownership for the memory from a std::string via std::move
                 Key: ARROW-3250
                 URL: https://issues.apache.org/jira/browse/ARROW-3250
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney
             Fix For: 0.12.0


There are instances where it is useful to be able retain ownership to a {{std::string}} owned by another as a {{arrow::Buffer}}, so we could have an interface like {{StlStringBuffer(std::string&& input)}} and transfer the memory that way
