Base class for document compressors.
This abstraction is primarily used for post-processing of retrieved documents.
Documents matching a given query are first retrieved. Then the list of documents can be further processed.
For example, one could re-rank the retrieved documents using an LLM.
Note users should favor using a RunnableLambda instead of sub-classing from this interface.
Create a new model by parsing and validating input data from keyword arguments.
Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.
self is explicitly positional-only to allow self as a field name.
