How Rust Monomorphization Works and Why It Bloats Your Binary Size

This video explains how Rust monomorphization works under the hood and why generics can increase binary size. We explore how the compiler generates multiple concrete versions of generic functions, when inlining removes symbols, and how these optimizations impact final binary output, performance, and debugging in release builds.
