Memoize Go functions on the fly

Memo

memo is a Go library for memoization.

Installation

go get github.com/quantumsheep/memo

Example

This is an example of how to use memo to memoize the Fibonacci function.

func fib(n int) int {
    return memo.Memoize(func() int {
        if n < 2 {
            return n
            }

        return fib(n-1) + fib(n-2)
    }, n)
}

The first argument to memo.Memoize is a closure that returns a value. The next arguments are dependencies to be compared when determining whether to use the cached value or not.
