Workaround for conflicting implementations of trait

[sacred coral]

I would to like to make this playground compile: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=88eb6c681d52851eb151d85a397ad1ff

Is there a workaround for making it work on stable

AFAIK there is no way to tell the Rust language what you need to tell it; however, you might be interested in the trait (FromIterator)[https://doc.rust-lang.org/std/iter/trait.FromIterator.html]

one way would be https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=ef5d2f9ef11eced7121219739845d27c
