Something which is neither a tuple struct nor a tuple variant was used as a
pattern.
Erroneous code example:
```compile_fail,E0164
enum A {
B,
C,
}
impl A {
fn new() {}
}
fn bar(foo: A) {
match foo {
A::new() => (), // error!
_ => {}
}
}
```
This error means that an attempt was made to match something which is neither a
tuple struct nor a tuple variant. Only these two elements are allowed as a
pattern:
```
enum A {
B,
C,
}
impl A {
fn new() {}
}
fn bar(foo: A) {
match foo {
A::B => (), // ok!
_ => {}
}
}
```
