Description

I have become a fan of Vavr for the "use values to represent flow control" model. Are there any plans to provide native support for Vavr types such as Option in Micronaut? More generally, is it practical for a user to add support for new extensions to the Micronaut infrastructure, as (for example) the various ArgumentHandler interfaces in Spring?

Research direction
This issue asks whether Micronaut plans to support Vavr types like Option. There is no concrete implementation proposal. To move forward, a contributor should investigate how Micronaut handles type conversion or argument binding (e.g., ArgumentHandler interfaces) and see if a custom adapter for Vavr Option can be added. Review the Micronaut core extension mechanisms and any existing third party integrations. The issue is old and has only one comment, so maintainer input may be needed to clarify if such a contribution would be accepted.
