+
+.. js:class:: ICU4XCodePointMapData16
+
+    An ICU4X Unicode Map Property object, capable of querying whether a code point (key) to obtain the Unicode property value, for a specific Unicode property.
+
+    For properties whose values fit into 16 bits.
+
+    See the `Rust documentation for properties <https://docs.rs/icu/latest/icu/properties/index.html>`__ for more information.

+
+    .. js:method:: get(cp)
+
+        Gets the value for a code point.

+        See the `Rust documentation for get <https://docs.rs/icu/latest/icu/properties/maps/struct.CodePointMapDataBorrowed.html#method.get>`__ for more information.
+
+
+    .. js:method:: get32(cp)
+
+        Gets the value for a code point (specified as a 32 bit integer, in UTF-32)
+
+
+    .. js:method:: iter_ranges_for_value(value)
+
+        Produces an iterator over ranges of code points that map to ``value``
+

+
+
+    .. js:method:: get_set_for_value(value)
+
+        Gets a :js:class:`ICU4XCodePointSetData` representing all entries in this map that map to the given value
+
+        See the `Rust documentation for get_set_for_value <https://docs.rs/icu/latest/icu/properties/maps/struct.CodePointMapDataBorrowed.html#method.get_set_for_value>`__ for more information.

+
+
+.. js:class:: ICU4XCodePointMapData8
+
+    An ICU4X Unicode Map Property object, capable of querying whether a code point (key) to obtain the Unicode property value, for a specific Unicode property.
+
+    For properties whose values fit into 8 bits.
+
+    See the `Rust documentation for properties <https://docs.rs/icu/latest/icu/properties/index.html>`__ for more information.

+
+    .. js:method:: get(cp)
+
+        Gets the value for a code point.

+
+        Gets the value for a code point (specified as a 32 bit integer, in UTF-32)
+
+
+    .. js:function:: general_category_to_mask(gc)
+
+        Converts a general category to its corresponding mask value
+
+        Nonexistant general categories will map to the empty mask
+
+        See the `Rust documentation for GeneralCategoryGroup <https://docs.rs/icu/latest/icu/properties/struct.GeneralCategoryGroup.html>`__ for more information.

+
+
+    .. js:method:: iter_ranges_for_mask(mask)
+
+        Given a mask value (the nth bit marks property value = n), produce an iterator over ranges of code points whose property values are contained in the mask.
+
+        The main mask property supported is that for General_Category, which can be obtained via ``general_category_to_mask()`` or by using ``ICU4XGeneralCategoryNameToMaskMapper``
+
+        Should only be used on maps for properties with values less than 32 (like Generak_Category), other maps will have unpredictable results
