Settings View Source WithClauseError exception (Elixir v1.16.0-rc.0)

An exception raised when a term in a with/1 expression does not match any of the defined -> clauses in its else.

The following fields of this exception are public and can be accessed freely:

• :term (term/0) - the term that did not match any of the clauses

For example, this exception gets raised for a with/1 like the following, because the {:ok, 2} term does not match the :error or {:error, _} clauses in the else:

with {:ok, 1} <- {:ok, 2} do
  :woah
else
  :error -> :error
  {:error, _} -> :error
end
