Permutation

[binh-vu]

Hi,

Thank you for making this awesome library. It would be great if you can support permutate function like in python

Thanks!

You should be able to get the same effect with repeat_n(iter, count).multi_cartesian_product().
That would repeat items within an iteration, e.g. "000", which permutations should exclude. So my suggestion is incorrect.

I've implemented this function, and will put up a pull request soon, although I have no idea how long it'll be until merge.

In the meantime, you can use my branch in your Cargo.toml (or copy it to your fork) if you need it:

[dependencies]
itertools = { git = "https://github.com/tobz1000/rust-itertools", branch = "permutations" }
