Error code E0508

A value was moved out of a non-copy fixed-size array.

Erroneous code example:

struct NonCopy; fn main() { let array = [NonCopy; 1]; let _value = array[0]; // error: cannot move out of type `[NonCopy; 1]`, // a non-copy fixed-size array }

The first element was moved out of the array, but this is not possible because NonCopy does not implement the Copy trait.

Consider borrowing the element instead of moving it:

struct NonCopy; fn main() { let array = [NonCopy; 1]; let _value = &array[0]; // Borrowing is allowed, unlike moving. }

Alternatively, if your type implements Clone and you need to own the value, consider borrowing and then cloning:

#[derive(Clone)] struct NonCopy; fn main() { let array = [NonCopy; 1]; // Now you can clone the array element. let _value = array[0].clone(); }

If you really want to move the value out, you can use a destructuring array pattern to move it:

struct NonCopy; fn main() { let array = [NonCopy; 1]; // Destructuring the array let [_value] = array; }
