ArgumentError exception (Elixir v1.19.0-dev)

An exception raised when an argument to a function is invalid.

You can raise this exception when you want to signal that an argument to a function is invalid. For example, this exception is raised when calling Integer.to_string/1 with an invalid argument:

iex> Integer.to_string(1.0)
** (ArgumentError) errors were found at the given arguments:

* 1st argument: not an integer

  :erlang.integer_to_binary(1.0)

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