Contract
- assert OnceCell::try_insert returns Ok(&T) on success and Err((&T, T)) with the existing reference and rejected value on collision instead of Err(T)
- assert OnceCell::set returns Result<(), T> without handing back a reference to the stored value
- assert Lazy::into_value on an uninitialized Lazy returns Err(F) without calling the initializer closure, and returns Ok(T) only after initialization
- assert Lazy::get returns None prior to forced evaluation without triggering the closure
- assert OnceCell does not become poisoned when get_or_init panics and allows subsequent initializations to retry and succeed
- assert OnceCell with &mut access can be modified in-place via get_mut and reset to empty via take for re-initialization
