Expand in-place iteration specialization to Flatten, FlatMap and ArrayChunks This enables the following cases to collect in-place: ```rust let v = vec![[0u8; 4]; 1024] let v: Vec<_> = v.into_iter().flatten().collect(); let v: Vec<Option<NonZeroUsize>> = vec![NonZeroUsize::new(0); 1024]; let v: Vec<_> = v.into_iter().flatten().collect(); let v = vec![u8; 4096]; let v: Vec<_> = v.into_iter().array_chunks::<4>().collect(); ``` Especially the nicheful-option-flattening should be useful in real code. |
