Signature

def _lazy_valid_checks(*args, throw = False, warning = False, materialize = False, xp)

Validate a set of conditions on the contents of possibly lazy arrays.

args : tuples of (Array, str): The first element of each tuple must be a 0-dimensional Array that evaluates to bool; the second element must be the message to convey if the first element evaluates to True.
throw: bool: Set to True to raise ValueError(args[i][1]) if args[i][0] is True.
warning: bool: Set to True to issue a warning with message args[i][1] if args[i][0] is True.
materialize: bool: Set to True to force materialization of lazy arrays when throw=True or warning=True. If the inputs are lazy and materialize=False, ignore the throw and warning flags.
xp: module: Array API namespace

: If xp is an eager backend (e.g. numpy) and all conditions are False, return True.
: If throw is True, raise. Otherwise, return False.
: If xp is a lazy backend (e.g. Dask or JAX), return a 0-dimensional bool Array.
