Build a geohash R package using Rust

We cover more advanced Rust concepts to build a package to perform geohashing in R. You'll learn how to:
• Using match statements for control flow
• Creating and working with custom structs
• Deriving traits for added functionality on your structs
• Implementing the From trait for custom structs
• Destructure tuples
• Vectorization across two variables
• Handling NAs effectively
• Generating data.frames from a vector of structs
If you're ready to enhance your Rust skills and create a powerful R package, this video is for you. Subscribe for more advanced Rust tutorials! 🛠️💻

Nice library 🎉.

How does one document functions exported from rextendr::document() so the document is readable and can be a reference used in Rstudio? Seeing the arguments are referred to as C objects?

[@josiahparry]

I'm not sure I follow with the last part of "arguments are referred to as C objects" There's a couple ways to do this. Personally, I like to write wrappers around my Rust functions so I can do better argument validation with {rlang}. So I use roxygen comments like normal. But you can also use roxygen comments in rust too!! You just add `///` which is a doc comment in rust. For example above the function write /// This is my function title /// /// this is my function description /// @param x a list /// @export

2:02, 16:19, etc What are you typing here to autocomplete typing? Is it some VS code Rust extension?

[@josiahparry]

Are you referring to the type hints? That’s the inlay hints from the rust analyzer!

[@JordiRosell]

​@@josiahparry yeah. I'm just starting / willing to start in rust, so this is why I ask newie questions.

[@josiahparry]

@@JordiRosell would a video on setting up VS Code for Rust help? TL;DR install the following extensions - rust-analyzer - Better Toml - todo tree (personal opinion on this one)
