🔍 Common Types - Intelligent Type System Foundation

THE DNA OF AI TYPE INTELLIGENCE

Welcome to Common Types - the revolutionary type system that transforms simple data types into intelligent, self-validating, and context-aware type definitions. This isn’t just another typing module; it’s a sophisticated type intelligence platform where every type carries semantic meaning, validates automatically, and evolves with your application’s understanding of data relationships.

⚡ REVOLUTIONARY TYPE INTELLIGENCE

Common Types represents a paradigm shift from static type definitions to living, intelligent type systems that understand context and adapt to usage:

🧠 Semantic Type Understanding: Types that know their meaning and relationships 🔄 Dynamic Type Evolution: Type definitions that grow smarter with usage ⚡ Automatic Validation: Self-validating types with intelligent error messages 📊 Context-Aware Casting: Smart type conversion based on semantic understanding 🎯 Protocol Intelligence: Advanced protocol definitions with runtime checking

🎓 BEST PRACTICES

1. Use Semantic Types: Choose types that convey meaning, not just structure

2. Enable Validation: Add validation to prevent data corruption early

3. Design for Evolution: Create types that can grow more intelligent

4. Leverage Protocols: Use protocols for flexible, runtime-checkable interfaces

5. Add Context Awareness: Make types adapt to their usage context

6. Monitor Performance: Track type operation performance and optimize

7. Document Relationships: Clearly define relationships between types

Common Types: Where Data Types Become Intelligent Semantic Entities 🔍

class haive.core.common.types.ABCRootWrapper(root=PydanticUndefined)

Bases: RootModel[TypeVar], Generic[T], ABC

Abstract base class for root-wrapped models that serialize with a named key. (like ‘query’ instead of ‘root’).

The key is inferred automatically from the class name (lowercased), unless explicitly overridden by setting SERIALIZED_KEY.

Examples

class Query(ABCRootWrapper[str]):

# SERIALIZED_KEY = “query” # Optional override

Parameters:

root (RootModelRootType)

model_dump(*args, **kwargs)

Model Dump.

Returns:

Add return description]

Return type:

[TODO

model_dump_json(*args, **kwargs)

Model Dump Json.

Returns:

Add return description]

Return type:

[TODO

SERIALIZED_KEY: ClassVar[str | None] = None

model_config: ClassVar[ConfigDict] = {}

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
