Adds support for memoizing functions.
@since 3.2.0
Memoizes the method with the given name. The modified method will cache the results of the original method, so that calling a method twice with the same arguments will short-circuit and return the cached results immediately.
Memoization assumes that the current object as well as the function arguments are immutable. Mutating the object or the arguments will not cause memoized methods to recalculate their results. There is no way to un-memoize a result, and calculation results will remain in memory even if they are no longer needed.
@example A fast fib function due to memoization
class FibFast extend Nanoc::Memoization def run(n) if n == 0 0 elsif n == 1 1 else run(n-1) + run(n-2) end end memoize :run end
@param [Symbol, String] method_name The name of the method to memoize
@return [void]
