Nikita Pekin 68f3415dd5 impr(LazyCell): return Err(value) on full cell ... Modify the `fill()` method of the `LazyCell` struct to return `Err(value)` when attempting to fill an already filled `LazyCell`. This is a replacement for the previous behaviour, which would return a panic instead. The new behaviour is preferred because it allows downstream crates to handle the error case better. Modify tests to accomodate changes in the error behaviour of the `fill()` method of the `LazyCell` struct. BREAKING CHANGE: the `fill()` method of the `LazyCell` struct now returns a `Result<(), T>`, which must be handled. The previous behaviour was to simply panic.		2016-08-17 03:08:28 -04:00
