bors 63bacf14cd Auto merge of #82162 - cuviper:flat-fold, r=Mark-Simulacrum ... Expand FlattenCompat folds The former `chain`+`chain`+`fold` implementation looked nice from a functional-programming perspective, but it introduced unnecessary layers of abstraction on every `flat_map`/`flatten` fold. It's straightforward to just fold each part in turn, and this makes it look like a simplified version of the existing `try_fold` implementation. For the `iter::bench_flat_map*` benchmarks, I get a large improvement in `bench_flat_map_chain_sum`, from 1,598,473 ns/iter to 499,889 ns/iter, and the rest are unchanged.		2021-02-25 00:36:05 +00:00
