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

   3 This error occurs when an attempt is made to partially reinitialize a
   4 structure that is currently uninitialized.
   5
   6 For example, this can happen when a drop has taken place:
   7
   8 ```compile_fail
   9 struct Foo {
  10     a: u32,
  11 }
  12 impl Drop for Foo {
  13     fn drop(&mut self) { /* ... */ }
  14 }
  15
  16 let mut x = Foo { a: 1 };
  17 drop(x); // `x` is now uninitialized
  18 x.a = 2; // error, partial reinitialization of uninitialized structure `t`
  19 ```
  20
  21 This error can be fixed by fully reinitializing the structure in question:
  22
  23 ```
  24 struct Foo {
  25     a: u32,
  26 }
  27 impl Drop for Foo {
  28     fn drop(&mut self) { /* ... */ }
  29 }
  30
  31 let mut x = Foo { a: 1 };
  32 drop(x);
  33 x = Foo { a: 2 };
  34 ```
