ModelAbortError

Error class representing an aborted model operation in LangChain.

This error is thrown when a model operation (such as invocation, streaming, or batching) is cancelled before it completes, commonly due to a user-initiated abort signal (e.g., via an AbortController) or an upstream cancellation event.

The ModelAbortError provides access to any partial output the model may have produced before the operation was interrupted, which can be useful for resuming work, debugging, or presenting incomplete results to users.
