bors 99d6692f6c Auto merge of #87431 - the8472:array-iter-fold, r=kennytm ... implement fold() on array::IntoIter to improve flatten().collect() perf With #87168 flattening `array::IntoIter`s is now `TrustedLen`, the `FromIterator` implementation for `Vec` has a specialization for `TrustedLen` iterators which uses internal iteration. This implements one of the main internal iteration methods on `array::Into` to optimize the combination of those two features. This should address the main issue in #87411 ``` # old test vec::bench_flat_map_collect ... bench: 2,244,024 ns/iter (+/- 18,903) # new test vec::bench_flat_map_collect ... bench: 172,863 ns/iter (+/- 2,141) ```		2021-07-27 10:38:41 +00:00
