View Source RuntimeError exception (Elixir v1.16.2)

An exception for a generic runtime error.

This is the exception that raise/1 raises when you pass it only a string as a message:

iex> raise "oops!"
** (RuntimeError) oops!

You should use this exceptions sparingly, since most of the time it might be better to define your own exceptions specific to your application or library. Sometimes, however, there are situations in which you don't expect a condition to happen, but you want to give a meaningful error message if it does. In those cases, RuntimeError can be a good choice.

Fields

RuntimeError exceptions have a single field, :message (a String.t/0), which is public and can be accessed freely when reading or creating RuntimeError exceptions.
