ArgumentError exception (Elixir v1.19.1)

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:
...

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.
