cargo-edit VS anyhow

“cargo add” from https://github.com/killercup/cargo-edit has that behavior, but not the built in one that was added to cargo

I have also noticed that the last commit of cargo-edit crate's GitHub repo (https://github.com/killercup/cargo-edit) was two days ago (pretty recent.) So it is probably relevant for a lot of people.

cargo-upgrade from cargo-edit (somewhat more intentional than builtin update)

I've also tried cargo-upgrade from cargo-edit like so:

You can also see how other crates do it. For example, cargo-edit is just like that - a single package with a library with a couple of small cli wrappers around it. You can compare their Cargo.toml to yours, maybe there is something different about them.

Just to check, are you aware of cargo-edit's cargo-set-version or cargo-release?

Speaking of cargo remove, see also cargo-edit [0] from which adding and removing originally came, as well as cargo-binstall [1] which installs binaries rather than compiling from source every time. The binaries are updatable with cargo-update [2].

The latter two can replace a package manager for Rust related utilities, as I often find that those in OS package repositories are often not as up to date as directly from cargo.

For context, it was/is part of cargo-edit crate which provides other nice functionalities as well. Hope all gets integrated in time.

https://github.com/killercup/cargo-edit can use the F option

Depending on your use case, thiserror and/or anyhow.

There is ? as well as the anyhow(https://github.com/dtolnay/anyhow) crate that deals with long nested result chains.

There are crates out there that help you reduce this boiler plate. thiserror is good for creating custom errors and color-eyre or anyhow are good for dynamic errors.

Give anyhow a look.

I've brought anyhow::Result into scope, making error handling super easy to use. We don't need to specify all our Error types. It can automatically convert any errors that implement std::error::Error, which should be all of them. If an error propagates all the way up to main(), we'll get all the info it's captured printed to stdout.

Alternatively, if you've got a lot of error types and you're outside a library (so directly in a binary where you don't plan to reuse code elsewhere) you can use anyhow. This gives you an error type you can basically propagate any other error through. On top of that you can attach context information at every return. It's basically a more complicated Result>.

One approach is to define a separate error type for each crate and then use anyhow, eyre or Box to wrap the error, whever a function can return errors originating in several different crates.

Have you tried anyhow and thiserror for making it as simple as .context("Message") or ? to type-convert and propagate errors up the call stack?
