Creating whatever errors.

[dpc]

What's the easiest way to create a Whatever? Basically whatever!-like macro but without built in return ?

I wouldn't say it's easy, but I'd expect that something like

use snafu::{Whatever, FromString};
let w = Whatever::without_source("oops".to_owned());

What's your usecase for creating the error without returning?

[dpc]

I'm using:

None.whatever_context("Invalid peer_pubkey")

so far, and seems a bit shorter. I was hoping for something ... even better.

I have database transaction wrapping type. Result<t, DatabaseError<E>>. So I actually need:

                None.whatever_context("Invalid peer_pubkey")
                    .context(TxSnafu)?

when that inner E is a Whatever. I know, I did it to myself, but it mostly works great.

There are times where I've created multiple levels of errors in one function, but I almost always end up rewriting them as multiple functions anyway. If you did that, then returning early would no longer be a pain.

[dpc]

I can't. Or at least it's a best thing I can figure out for other reasons. Even creating whatever here is not such a big deal, but I thought it's worth asking.

BTw. anyhow has both anyhow! and bail!, and bail is the one with a return, so to me it wa a little bit ... surprising that whatever! does inner early return.

I can make my own macro, so I'm probably going to do that, but just reporting feedback and checking if I haven't missed anything. Thanks a lot!
