TypeChecker class abstract

An abstraction around doing static type checking at compile/build time.

The abstractions are borrowed from the source_gen package. This class provides methods to check type compatibility, examine annotations, and perform other type-related operations.

Constructors

TypeChecker.any(Iterable<TypeChecker> checkers)
Creates a new TypeChecker that can check against the given type.
