------------------------------------------------
Summary: Implement utility method to identify lossless casts
Key: CALCITE-1760
URL: https://issues.apache.org/jira/browse/CALCITE-1760
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Priority: Minor
Implement utility method to identify 'lossless' casts, i.e., casts from which the original
value of the field can be certainly recovered?
For instance, int -> bigint is true (as you can cast back to int without loss of information),
however bigint -> int is false.
