On memoization


Using “open” recursion:

  • We can separate memoization logic from function logic.
  • We can memoize functions without modifying the syntax of the function.
  • We can make functions generic across multiple types of memoization.

Memoization in Rust.

Consider a recursive function. The most basic example is the Fibonacci sequence. Here is a naive implementation:

fn fib_naive(arg: u32) -> u32 {
match arg {
0 => 0,
1 => 1
