harshkumar-2005 opened a new pull request, #47922:
URL: https://github.com/apache/arrow/pull/47922
### Rationale
Introduces a `type_singleton(Type::type id)` utility to create
parameter-free DataType instances
(such as int32, boolean, utf8, etc.) without requiring parameters. Returns
an error for
parameterized or unsupported types.
### Implementation Details
- Added implementation in `type_traits.cc`
- Declared function in `type_traits.h`
- Added comprehensive tests for:
- Parameter-free types (success cases)
- Parameterized types (expected error)
- Invalid type IDs (graceful error handling)
### Testing
All tests in `arrow-type-test` passed locally:
### Notes
This utility simplifies internal code where parameter-free type instances
are required.
