[jira] [Created] (ARROW-12788) [C++] arrow::compute::Expression::type_id() function

Ian Cook created ARROW-12788:
--------------------------------

             Summary: [C++] arrow::compute::Expression::type_id() function
                 Key: ARROW-12788
                 URL: https://issues.apache.org/jira/browse/ARROW-12788
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Ian Cook
            Assignee: Ben Kietzman


There is a function {{type()}} that returns the type of a post-bind {{Expression}} as a {{std::shared_ptr<arrow::DataType>}}:
 [https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/exec/expression.h#L105]

It would be convenient to also have a function {{type_id()}} that returns this as an {{arrow::Type::type}}.
