    Parameters
    ----------
    parameter_constraints : dict or {"no_validation"}
        If "no_validation", validation is skipped for this parameter.

        If a dict, it must be a dictionary `param_name: list of constraints`.
        A parameter is valid if it satisfies one of the constraints from the list.
        Constraints can be:
        - an Interval object, representing a continuous or discrete range of numbers
        - the string "array-like"
        - the string "sparse matrix"
        - the string "random_state"
        - callable
        - None, meaning that None is a valid value for the parameter
        - any type, meaning that any instance of this type is valid
        - an Options object, representing a set of elements of a given type
        - a StrOptions object, representing a set of strings
        - the string "boolean"
        - the string "verbose"
        - the string "cv_object"
        - the string "missing_values"
        - a HasMethods object, representing method(s) an object must have
        - a Hidden object, representing a constraint not meant to be exposed to the user

    params : dict
        A dictionary `param_name: param_value`. The parameters to validate against the
        constraints.

    caller_name : str
        The name of the estimator or function or method that called this function.

S )r=   uU  Constraint representing a typed interval.

    Parameters
    ----------
    type : {numbers.Integral, numbers.Real, "real_not_int"}
        The set of numbers in which to set the interval.

        If "real_not_int", only reals that don't have the integer type
        are allowed. For example 1.0 is allowed but 1 is not.

    left : float or int or None
        The left bound of the interval. None means left bound is -âˆž.

    right : float, int or None
        The right bound of the interval. None means right bound is +âˆž.

    closed : {"left", "right", "both", "neither"}
        Whether the interval is open or closed. Possible choices are:

        - `"left"`: the interval is closed on the left and open on the right.
          It is equivalent to the interval `[ left, right )`.
        - `"right"`: the interval is closed on the right and open on the left.
          It is equivalent to the interval `( left, right ]`.
        - `"both"`: the interval is closed.
          It is equivalent to the interval `[ left, right ]`.
        - `"neither"`: the interval is open.
          It is equivalent to the interval `( left, right )`.

    Notes
    -----
    Setting a bound to `None` and setting the interval closed is valid. For instance,
    strictly speaking, `Interval(Real, 0, None, closed="both")` corresponds to
    `[0, +âˆž) U {+âˆž}`.

aÈ  Return a value that does not satisfy an interval constraint.

    Generating an invalid value for an integer interval depends on the other constraints
    since an int is a real, meaning that it can be valid for a real interval.
    Assumes that there can be at most 2 interval constraints: one integer interval
    and/or one real interval.

    This is only useful for testing purpose.

    Parameters
    ----------
    interval : Interval instance
        The interval to generate a value for.

    constraints : list of _Constraint instances
        The list of all constraints for this parameter.

    Returns
    -------
    val : object
        A value that does not satisfy the interval constraint.
