So I'm currently learning the Rust language on the official website and I'm in the middle of Chapter 12 where they want me to split some of my code from src/main.rs to src/lib.rs. At first I created a library crate named "minigrep" inside the binary crate:

minigrep
src
- main.rs

but Rust couldn't find it. Next I tried moving it inside the src directory:

src
- minigrep
- main.rs

Any help as to how Rust can detect an external crate?

I think the tutorial is expecting you to create a file called `lib.rs` right next to `main.rs`. – Peter Hall Aug 18 '18 at 19:45
@PeterHall I went through this tutorial myself last week, and your comment is the answer. – John H Aug 18 '18 at 19:47
This isn't anything to do with an external crate. This is just organising code within your project - no external crates involved. – Peter Hall Aug 18 '18 at 19:50
@PeterHall It works thanks! – toobie Aug 18 '18 at 23:38
