Thoughts about adding map for tokio::sync::mpsc::error::TrySendError (and/or others)

[winestone]

Hi, would there be any objections or issues with adding map to tokio::sync::mpsc::error::TrySendError or other similar types? If not, I'm happy to make the relevant PRs.

Hopefully this isn't a duplicate, I've searched the issues and discussions here but haven't found anything relevant.

Why would you want that?

Thanks for the quick reply! I think sometimes you may want to add more info or remove information and it may be nicer than doing a match.

The particular use case I had was that I wanted to create a wrapper around tokio::sync::mpsc::Sender<T> but which instead sends Us, leading to me mapping over the error.

But of course there is a cost in that you have to maintain it into the future so I understand if the costs outweigh the rare use-cases.

I think this is too niche. You can always define your own method for doing it.
