enum FieldUpdate

A sealed enumeration of field-level update operations.

Each variant describes how a single field should be modified during an Update action on a ProjectionAction.

Provides two APIs:

  • '''String-based''' (direct): FieldUpdate.Increment("user_count", 1L)
  • '''Selector-based''' (macro): FieldUpdate.increment[User](_.userCount) which maps userCount → user_count via SqlNameMapper.SnakeCase
