Yes. I prefer ‘snafu’ but there are a few, and you could always roll your own.

+1 for snafu. It lets you blend anyhow style errors for application code with precise errors for library code. .context/.with_context is also a lovely way to propagate errors between different Result types.

How does that compare to "this error for libraries and anyhow for applications"?

[smj-edison]

You don't have to keep converting between error types :)

Yeah, with SNAFU I try to encourage people going all-in on very fine-grained error types. I love it (unsurprisingly).
