AbstractStructReader and Struct contained multiple method definitions and calls that would trigger unnecessary object creation and auto-boxing on the happy path. This change removes those, sometimes at the expense of some duplicate code. This however reduces the number of object creations for the happy flow, which is by far the most used code path.

Code Review

This pull request refactors validation logic in AbstractStructReader and Struct by replacing Guava's checkState with manual exception throwing and utilizing ImmutableList and Type constants to reduce object allocation. It also introduces method overloads for validation that use column indices for error messages. Feedback highlights that changing the parameter type from Object to String in the protected checkNonNull method is a breaking change for subclasses and suggests maintaining backward compatibility by keeping the original signature as a deprecated overload.

AbstractStructReader and Struct contained multiple method definitions and calls that
would trigger unnecessary object creation and auto-boxing on the happy path. This
change removes those, sometimes at the expense of some duplicate code. This however
reduces the number of object creations for the happy flow, which is by far the most
used code path.
