Extra iterator adaptors, iterator methods, free functions, and macros.
Introduces new zip alternatives. I was making an application that uses something like `zip_squash` and thought it could be implemented here. Examples might be forming pairs from 2 sets of...
They're just convenience method, but avoid having to dereference individual variants, and may mitigate missing the `Only` case.
This is very similar to std’s `Iterator::clone()` / `Cloned`, but works on more types, such as `CStr` / `CString`.
Closes #998 Implementations for the following methods: - duplicates_with_hasher - duplicates_by_with_hasher - unique_with_hasher - unique_by_with_hasher - all_unique_with_hasher - into_group_map_with_hasher - into_group_map_by_with_hasher - into_grouping_map_with_hasher - into_grouping_map_by_with_hasher - counts_with_hasher - counts_by_with_hasher
Most of the changes are to create a common abstraction that works for `permutations` and `{array_,}combinations`, much of it by @phimuemue. Completes a variant of #1001.
There is the `combinations()` and `tuple_combinations()` functions, I'm however missing the `tuple_permutations()` function. Is there a reason this couldn't exist? If not, I might even be open to implementing it...
Implementation of an iterator adaptor that generates all unique multiset permutations for the given iterator. Based on the algorithm presented in [this paper by Aaron Williams](https://doi.org/10.1137/1.9781611973068.107). Pro: It is substantially...
Like the title says, a `multizip` version of `zip_longest`. Here's how I imagine it working: ```rust Enum AtLeastOneOf { One(i32), Two(i32, i32), Three(i32, i32, i32), Four(i32, i32, i32, i32), N(...),...
All adaptors bounded by `Hash` would potentially benefit from a `with_hasher` variant that allowed supplying a faster `Hasher` (e.g., `ahash` or `fxhash`): - [duplicates](https://docs.rs/itertools/latest/itertools/trait.Itertools.html#method.duplicates) - [ ] `duplicates_with_hasher` - [duplicates_by](https://docs.rs/itertools/latest/itertools/trait.Itertools.html#method.duplicates_by)...
