// Ensure that we cannot move into an uninitialized fixed-size array.
struct D { _x: u8 }
fn d() -> D { D { _x: 0 } }
fn main() {
foo(1);
foo(3);
}
fn foo(i: usize) {
let mut a: [D; 4];
On partial uninit error point at where we need init When a binding is declared without a value, borrowck verifies that all codepaths have *one* assignment to them to initialize them fully. If there are any cases where a condition can be met that leaves the binding uninitialized or we attempt to initialize a field of an unitialized binding, we emit E0381. We now look at all the statements that initialize the binding, and use them to explore branching code paths that *don't* and point at them. If we find *no* potential places where an assignment to the binding might be missing, we display the spans of all the existing initializers to provide some context.
