Implement Clone for Iter/Values/Key of storage types

[fadeevab]

Currently, cycle() is not possible to use, because Clone is not implemented for Iter.

let store = UnorderedMap::new(b'a');
store.iter().cycle(); // <--- ERROR

cycle() requires the iterator object to be clonable itself. Like it's implemented in the standard collections.

let store = vec![];
store.iter().cycle(); // <--- OK

Thank you!

Hey @g4titanx!
Thanks for showing interest.
We've created an application for you to contribute to near-sdk-rs.
Go check it out on OnlyDust!

I wasn't able to apply thru ODhack
I would still love to work on it anyways

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

I am a software engineer proficient with C, JavaScript, TypeScript, and Python. I started writing Rust a month ago, and from the issue, where cycle() method will need to iter() requires the iterator object to be clonable, I believe I should be able to resolve the issue.

How I plan on tackling this issue

• I will first consult the documentation (Rust Book) and look up on the iter() method.
• Make more research to see if there is anyway the iterator object from the iter() method be clonable.
• Test whatsoever findings I get.
• Keep at it until it works just fine and compiled successfully.

I am a backend developer who specialises in django(a python module). I have intensive knowledge in Python and I reckon I can solve this problem.

How I plan on tackling this issue

I would make use of my intensive knowledge in Python and make more research to fix your problem and the problem isn't so complex. Desired results would be achieved in less than 48 hours.

hi @frol , all the storage types are in this crate near-sdk/src/store, right?

[frol]

@g4titanx Yes, please

[g4titanx]

okay, great!
