Module Contents

class haive.core.engine.document.loaders.strategy.LoaderCapability[source]

Bases: str, enum.Enum

Initialize self. See help(type(self)) for accurate signature.

class haive.core.engine.document.loaders.strategy.LoaderPriority[source]

Bases: str, enum.Enum

Initialize self. See help(type(self)) for accurate signature.

class haive.core.engine.document.loaders.strategy.LoaderStrategy(/, **data)[source]

Bases: pydantic.BaseModel

Information about a document loader strategy.

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.

Parameters:

data (Any)

check_availability()[source]

Check if this loader strategy is available.

Return type:

bool

create_loader(source, options)[source]
