    Module●Since v0.1

    beta_decorator

    Helper functions for marking parts of the LangChain API as beta.

    This module was loosely adapted from matplotlib's _api/deprecation.py module.

    Warning

    This module is for internal use only. Do not use it in your own code. We may change the API at any time with no warning.

    Functions

    function
    is_caller_internal

    Return whether the caller at depth of this function is internal.

    function
    beta

    Decorator to mark a function, a class, or a property as beta.

    When marking a classmethod, a staticmethod, or a property, the @beta decorator should go under @classmethod and @staticmethod (i.e., beta should directly decorate the underlying callable), but over @property.

    When marking a class C intended to be used as a base class in a multiple inheritance hierarchy, C must define an __init__ method (if C instead inherited its __init__ from its own base class, then @beta would mess up __init__ inheritance when installing its own (annotation-emitting) C.__init__).

    function
    suppress_langchain_beta_warning

    Context manager to suppress LangChainDeprecationWarning.

    function
    warn_beta

    Display a standardized beta annotation.

    function
    surface_langchain_beta_warnings

    Unmute LangChain beta warnings.

    Classes

    class
    LangChainBetaWarning

    A class for issuing beta warnings for LangChain users.
