stuck at "unresolved import" Rust Embedded - intellij-idea

Question

I am new to Rust and I am working in embedded development. I am making a project to blink the led of the stmf3 board. But I am getting errors while using the command cargo build
This Repo contains my code and structure. I am really stuck here. Can someone please a way to solve this?
The error I am getting is:
error[E0433]: failed to resolve: unresolved import
