+Repeated Warning Suppression Criteria
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The filters that suppress repeated warnings apply the following criteria to determine if a warning is considered a repeat:
+
+- ``"default"``: A warning is considered a repeat only if the (*message*, *category*, *module*, *lineno*) are all the same.
+- ``"module"``: A warning is considered a repeat if the (*message*, *category*, *module*) are the same, ignoring the line number.
+- ``"once"``: A warning is considered a repeat if the (*message*, *category*) are the same, ignoring the module and line number.
