• thiserror

  14 4,002 8.7 Rust

  derive(Error) for struct and enum error types

What is the benefit of splitting a proc-macro crate into (usually) two crates, proc_macro_crate and proc_macro_crate_impl? Why not just have one crate? Does it offer any benefits to to overall compilation times? An example of this can be seen in the thiserror crate where there's a thiserror and thiserror_impl crate.

• example-electron-license-activation

  4 82 0.0 JavaScript

  An example of how to implement software licensing and device activation in an Electron application

  

I’m currently developing a commercial product with Rust and I was wondering what the best way to distribute and sell licenses for it is. Should I use a third party like keygen or is there an easy way I could get started on implementing my own. I’m out of my depth when it comes to software licensing so I figure I should ask before assuming it’s a task I can take on myself.

• rand

  29 1,568 8.2 Rust

  A Rust library for random number generation.

  

Some wasm targets can’t generate random numbers at all but in the case of the book because you are using wasm in a browser you can use JS to generate random numbers. I believe there’s a way to get the rand crate to use JS as the backend for generating rand but its a bit more convoluted than the easy one-liner that the book suggests.
