Event Reference
-----------------
These events function similar to :ref:`the regular events <discord-api-events>`, except they
are custom to the command extension module.
.. function:: on_command_error(ctx, error)
An error handler that is called when an error is raised
inside a command either through user input error, check
failure, or an error in your own code.
A default one is provided (:meth:`.Bot.on_command_error`).
:param ctx: The invocation context.
:type ctx: :class:`Context`
:param error: The error that was raised.
:type error: :class:`CommandError` derived
.. function:: on_command(ctx)
An event that is called when a command is found and is about to be invoked.
This event is called regardless of whether the command itself succeeds via
error or completes.
:param ctx: The invocation context.
:type ctx: :class:`Context`
.. function:: on_command_completion(ctx)
An event that is called when a command has completed its invocation.
This event is called only if the command succeeded, i.e. all checks have
passed and the user input it correctly.
:param ctx: The invocation context.
:type ctx: :class:`Context`
