Description

__init__.__doc__

Construct an index object.

        :param name:
          The name of the index

        :param \*expressions:
          Column expressions to include in the index.   The expressions
          are normally instances of :class:`_schema.Column`, but may also
          be arbitrary SQL expressions which ultimately refer to a
          :class:`_schema.Column`.

        :param unique=False:
            Keyword only argument; if True, create a unique index.

        :param quote=None:
            Keyword only argument; whether to apply quoting to the name of
            the index.  Works in the same manner as that of
            :paramref:`_schema.Column.quote`.

        :param info=None: Optional data dictionary which will be populated
            into the :attr:`.SchemaItem.info` attribute of this object.

            .. versionadded:: 1.0.0

        :param \**kw: Additional keyword arguments not mentioned above are
            dialect specific, and passed in the form
            ``<dialectname>_<argname>``. See the documentation regarding an
            individual dialect at :ref:`dialect_toplevel` for detail on
            documented arguments.
