The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

CLI Shell Completions in Rust
We'll be updating our grab-xkcd program from a previous post with the new code, but in order to clearly demonstrate the different methods and not conflict with the original article I will use two new branches completions-ct for compile time completions, and completions-rt for run time completions. If the reader is feeling froggy, you can combine the two!

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.

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.

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 grab-xkcd and anyhow you can also consider the following projects:
structopt - Parse command line arguments by defining a struct.
eyre - A trait object based error handling type for easy idiomatic error handling and reporting in Rust applications
color-eyre - Custom hooks for colorful human oriented error reports via panics and the eyre crate
thiserror - derive(Error) for struct and enum error types
rust - Rust language bindings for TensorFlow
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
