Diving into Rust with a CLI

• structopt

  18 2,689 2.7 Rust

  Parse command line arguments by defining a struct.

We can do this all in just a few lines of Rust via the clap crate. However, for those familiar with the structopt crate, which allows one to define a Rust struct that contains all the CLI logic, as of clap 3.0 that code has been merged together. We will use the 3.0.0-beta.1 release of clap to demonstrate.

• anyhow

  13 5,071 8.5 Rust

  Flexible concrete Error type built on std::error::Error

To let main() handle our errors, it needs to return a Result as well. Since we'll be dealing all kinds of different errors from different crates, it's helpful to have some convenience methods and representation for handling all this. The anyhow crate does just this!
