A type with a `Drop` implementation was destructured when trying to initialize
a static item.
Erroneous code example:
```compile_fail,E0493
enum DropType {
A,
}
impl Drop for DropType {
fn drop(&mut self) {}
}
struct Foo {
field1: DropType,
}
static FOO: Foo = Foo { ..Foo { field1: DropType::A } }; // error!
```
The problem here is that if the given type or one of its fields implements the
`Drop` trait, this `Drop` implementation cannot be called during the static
type initialization which might cause a memory leak. To prevent this issue,
you need to instantiate all the static type's fields by hand.
```
enum DropType {
A,
}
impl Drop for DropType {
fn drop(&mut self) {}
}
struct Foo {
field1: DropType,
}
static FOO: Foo = Foo { field1: DropType::A }; // We initialize all fields
// by hand.
```
