cargo-edit VS cargo-script

“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

Accept BTC, all credit card * $1 .unwrap() - wallhack through Err * $2 .ok() - invisibility cheat for unused Result warning * $5 .unwrap_unchecked() - advanced wallhack, never fall out of map from panic For script console, just $10.

You can also use cargo script. After installing it you can just do

I think there are some projects in this area, eg, https://github.com/DanielKeep/cargo-script. For my personal scripts, I have a single Cargo.toml for a busy-box style multiplexed binary: https://github.com/matklad/config/blob/f0259ca8a3755f2e62a3bf472c2514fd6cb891ff/tool/src/main.rs#L16.

O seems that this does already exist: https://github.com/DanielKeep/cargo-script

You don't have to set up a project if you use cargo-script

Take a look at cargo script. That should/could do what you want

when I first started using rust, I knew python a lot better so I would write scripts with python. at this point though, I write a lot more rust than python these days, so I'll write pretty much everything with rust. cargo-script is a useful tool for this, as well as the self-compiling script: https://neosmart.net/blog/2020/self-compiling-rust-code/

Another option is cargo-script, which lets you run self contained rust files.
