Hi I have a project I am having trouble moving the mod system from 2015 rust to 2018.
The 2015 code simplified has a structure like
src --- lib.rs --- elements ---- mod.rs ---- element1.rs ---- element2.rs ---- element3.rs .........
mod.rs contained lines like
pub mod element1; pub mod element2; pub mod element3; ....
In lib.rs I had
pub mod elements;
The guide seems to indicate mod.rs is no longer needed
but the build returns
file not found for module `elements` --> src/lib.rs:25:9 | 25 | pub mod elements;
How can I declare multiple files under a subdirectory as modules ?
