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

             Summary: [Format] Define logical data type that represents a 
"packed C struct" composed from other fixed-size primitive types
                 Key: ARROW-1790
                 URL: https://issues.apache.org/jira/browse/ARROW-1790
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Format
            Reporter: Wes McKinney


This would embed data like

{code}
struct Point {
  double x;
  double y;
  double z;
};
{code}

Here the struct could be embedded in a {{FixedSizeBinary}} with width 24. This 
is similar to structured data types in NumPy and other libraries
