defmodule Xandra.Error do
@moduledoc """
An exception struct that represents an error returned by Cassandra.
For more information on when this error is returned or raised, see the
documentation for the `Xandra` module.
The `:reason` field represents the reason (as an atom) of the error. For
example, if the query you're trying to execute contains a syntax error,
`:reason` will be `:invalid_syntax`. The `:message` field is a string that
contains the exact error message that Cassandra returned.
Since this struct is an exception, it is possible to raise it with
`Kernel.raise/1`. If the intent is to format errors as strings (for
example, for logging purposes), it is possible to use `Exception.message/1` to
get a formatted version of the error.
