# Error code E0383

#### Note: this error code is no longer emitted by the compiler.

This error occurs when an attempt is made to partially reinitialize a structure that is currently uninitialized.

For example, this can happen when a drop has taken place:

    #![allow(unused)]
    fn main() {
    struct Foo {
        a: u32,
    }
    impl Drop for Foo {
        fn drop(&mut self) { /* ... */ }
    }

    let mut x = Foo { a: 1 };
    drop(x); // `x` is now uninitialized
    x.a = 2; // error, partial reinitialization of uninitialized structure `t`
    }

This error can be fixed by fully reinitializing the structure in question:

    #![allow(unused)]
    fn main() {
    struct Foo {
        a: u32,
    }
    impl Drop for Foo {
        fn drop(&mut self) { /* ... */ }
    }

    let mut x = Foo { a: 1 };
    drop(x);
    x = Foo { a: 2 };
    }
