No random tests + translation outdated + author long time inactive => rejected

Excellent point! This solution doesn't, and fails tests where over/under flow is a concern.

Filtering entries that may cause issues with s-i then allows the original algorithm to work.

How does this deal with the potential overflow in s-i?

assert_eq!( sum_pairs(&[10, -115], -125), Some((10, -115)) );

Seems to panic.

needs random tests

Amazing!

unapprovable due to changes in the description. Please fork the translation.

@g964 I will!

So I will approve it. Nevertheless you should ask CW to add some rand function:-)

@g964 See This crate is on crates.io and can be used by adding rand to the dependencies in your project's Cargo.toml line in Usage. This is a crate supported by the official rust-lang team, but that it is not (yet) in std.

Sorry:-( but I am seeing that: https://doc.rust-lang.org/rand/rand/index.html. Can't you use it?

The problem is, Rust has no rand in std, so writing random tests is a bit hard in Rust...
