Isaac Sheff commented on THRIFT-4005: ------------------------------------- At the moment, I intend to play with potential solutions at https://github.com/isheff/thrift/tree/THRIFT-4005 , but of course I can make no guarantees on my competence. > Better Haskell Support for Union Types in Thrift > ------------------------------------------------ > > Key: THRIFT-4005 > URL: https://issues.apache.org/jira/browse/THRIFT-4005 > Project: Thrift > Issue Type: Improvement > Components: Haskell - Compiler, Haskell - Library > Affects Versions: 1.0 > Reporter: Isaac Sheff > Priority: Minor > Labels: features > Fix For: 1.0 > > Original Estimate: 1m > Remaining Estimate: 1m > > Thrift's Haskell implementation presently expresses union types as product > types. While this is sufficient for functionality, and may mirror the way > Thrift works under the hood, it requires the programmer to write unnecessary > runtime checks and matches to find the filled field, and verify there is > precisely one. > I propose augmenting the existing Haskell Thrift system with union Haskell > types for union Thrift types, and augmenting the interface definitions so the > user can define a service in terms of either the legacy product types or the > new union types. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
