Learn how the Rust compiler can optimize some recursive calls into loops with tail call optimization of the recursive call.

The article covers:

  • How Tail Call Optimization (TCO) gets converted into a loop
  • How the Rust compiler can use a hybrid approach with recursion and loops
  • How the compiler optimizes away the enum discriminant when it can infer it from the surrounding context
