Rust Notes — Module 7
Rust Notes — Module 7: Packages, Crates & Modules 1. How Rust Compilation Works In C, you hand the compiler a list of files. Each file compiles independently, and a linker stitches the object files together. The problem — the compiler has no idea which files depend on which, so you need a Makefile to track what needs recompiling when something changes. Rust takes a different approach. You hand the compiler one root file (main.rs or lib.rs). The compiler follows mod declarations to find every other file that’s part of the crate. Because Rust knows the full dependency graph from the start, it handles incremental recompilation internally — no Makefile needed. ...
