Implementing Rust newtype for errors in axum (opens in new tab)

Great post. I do the same thing for all of my Rust web servers too. I don't use anyhow though, prefer rolling everything myself - which as you call out is a pain after a while.

would you get backtraces with this implementation? I've been increasingly frustrated with axum. It hits my custom error where I print something like "sqlx database failed" but when there's lots of traffic it's hard to determine which of the hundreds of queries actually failed. What I really want is the top part of a backtrace or at least a line number. I know anyhow gives bts but will it actually be useful when used like this?

Anyone else have ideas on how to solve this?

Like the post, but the backticks on all sorts of things is very distracting - am I missing some value here?
