## No matching case clause in Erlang
|
||
|
|
|
||
|
|
Reports an error when none of the clauses of a `case` match the expression. Corresponds to the `{case_clause,V}` error in the Erlang runtime.
|
||
|
|
|
||
|
|
For example, if we call `tail([])` and the full definition of `tail` is
|
||
|
|
```erlang
|
||
|
|
tail(X) ->
|
||
|
|
case X of
|
||
|
|
[_|T] -> T
|
||
|
|
end.
|
||
|
|
```
|
||
|
|
|
||
|
|
This error is reported if either the pattern(s) or the guard(s) prevent matching any of the clauses.
