I’ve been experimenting with Rust, so when I wanted a simple utility to add items to a global todo list, I created a directory called do and ran cargo init.
True to form, cargo surprised me with its attention to detail. I got this message in return:
Creating binary (application) package
error: the name `do` cannot be used as a package name, it is a Rust keyword
If you need a package name to not match the directory name, consider using --name flag.
If you need a binary with the name "do", use a valid package name, and set the binary name to be different from the package. This can be done by setting the binary filename to `src/bin/do.rs` or change the name in Cargo.toml with:
Kudos, Rust team! While I’m sure I would have figured it out eventually, this made it easy and obvious to avoid a simple pitfall.
