class BetaAsyncAbstractMemoryTool(BetaAsyncBuiltinFunctionTool):
"""Abstract base class for memory tool implementations.
"""Abstract base class for async memory tool implementations.

This class provides the interface for implementing a custom memory backend for Claude.
This class provides the interface for implementing a custom memory backend for Claude
with async/await support.

Subclass this to create your own memory storage solution (e.g., database, cloud storage, encrypted files, etc.).

Example usage:

```py
class MyMemoryTool(BetaAbstractMemoryTool):
def view(self, command: BetaMemoryTool20250818ViewCommand) -> BetaFunctionToolResultType:
class MyMemoryTool(BetaAsyncAbstractMemoryTool):
async def view(self, command: BetaMemoryTool20250818ViewCommand) -> BetaFunctionToolResultType:
...
return "view result"

def create(self, command: BetaMemoryTool20250818CreateCommand) -> BetaFunctionToolResultType:
async def create(self, command: BetaMemoryTool20250818CreateCommand) -> BetaFunctionToolResultType:
...
return "created successfully"

# ... implement other abstract methods
