Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Is this a good way of handling errors in Rust?
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.

Unwraps EVERYWHERE
No, that's right! I forgot about that, sorry. I took a look again and the difference seems to be https://docs.rs/eyre/0.6.5/eyre/trait.EyreHandler.html, which allows one to change the way how Errors/Reports are shown. A good example for that is color-eyre.

How to debug Just My Code in Vscode?
Definitely more on the application ecosystem side, but I’ve personally found the combination of the tracing (https://tracing-rs.netlify.app/tracing/) crate (especially with liberal use of the instrument macro - https://tracing-rs.netlify.app/tracing/attr.instrument.html ) , color-eyre (https://github.com/yaahc/color-eyre — adding contexts as I bubble up errors ) and then wiring the whole thing up so I get tracing log entries, and spantraces / stacktraces just seems to provide me enough visibility. Most of my code has been running in async/tokio, so I have no idea what the debugging experience would even be across await points.

Rust: Structuring and handling errors in 2020 (2020)
Another crate to mention - eyre and color-eyre, basically a port of anyhow but a few bells and whistles, and an awesome colored error report formatter.

I love building a startup in Rust. I wouldn't pick it again.
Depending on your use case, thiserror and/or anyhow.

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

Looking for general advice on toy project
Give anyhow a look.

Oops, I Did It Again...I Made A Rust Web API And It Was Not That Difficult
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.

Idiomatic way to return/break if Err/None
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>.
-
Using workspace for modularization is kind of painful?
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.
-
Can we please stop downvoting people who dislike Rust?
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?
What are some alternatives?
When comparing color-eyre and anyhow you can also consider the following projects:
thiserror - derive(Error) for struct and enum error types
eyre - A trait object based error handling type for easy idiomatic error handling and reporting in Rust applications
gh-labels-cli - A CLI for managing labels in existing GitHub repositories
rust - Rust language bindings for TensorFlow
structopt - Parse command line arguments by defining a struct.
cargo-edit - A utility for managing cargo dependencies from the command line.
hyper - An HTTP library for Rust
fenix - Rust toolchains and rust-analyzer nightly for Nix [maintainer=@figsoda]
todo-mvp - The non-SPA version of the todo list app
rust - Empowering everyone to build reliable and efficient software.
Cargo - The Rust package manager
