web3research.common.ChainStyle
==============================

.. py:class:: web3research.common.ChainStyle(*args, **kwds)

   Bases: :py:obj:`enum.Enum`


   Create a collection of name/value pairs.

   Example enumeration:

   >>> class Color(Enum):
   ...     RED = 1
   ...     BLUE = 2
   ...     GREEN = 3

   Access them by:

   - attribute access::

   >>> Color.RED
   <Color.RED: 1>

   - value lookup:

   >>> Color(1)
   <Color.RED: 1>

   - name lookup:

   >>> Color['RED']
   <Color.RED: 1>

   Enumerations can be iterated over, and know how many members they have:

   >>> len(Color)
   3

   >>> list(Color)
   [<Color.RED: 1>, <Color.BLUE: 2>, <Color.GREEN: 3>]

   Methods can be added to enumerations, and members can have their own
   attributes -- see the documentation for details.


   .. py:attribute:: BTC
      :value: 'btc'



   .. py:attribute:: ETH
      :value: 'eth'



   .. py:attribute:: TRON
      :value: 'tron'
