Caching Function Examples

CacheWrapper

A non-thread-safe caching decorator

package main

import (
	"fmt"
	"math/big"
	"github.com/kashifkhan0771/utils/math"
)

// Example function: Compute factorial
func factorial(n int) *big.Int {
	result := big.NewInt(1)
	for i := 2; i <= n; i++ {
		result.Mul(result, big.NewInt(int64(i)))
	}
	return result
}

func main() {
	cachedFactorial := utils.CacheWrapper(factorial)
	fmt.Println(cachedFactorial(10))
}

Output:

3628800

SafeCacheWrapper

A thread-safe caching decorator

package main

import (
	"fmt"
	"math/big"
	"github.com/kashifkhan0771/utils/math"
)

// Example function: Compute factorial
func factorial(n int) *big.Int {
	result := big.NewInt(1)
	for i := 2; i <= n; i++ {
		result.Mul(result, big.NewInt(int64(i)))
	}
	return result
}

func main() {
	cachedFactorial := utils.SafeCacheWrapper(factorial)
	fmt.Println(cachedFactorial(10))
}

Output:

3628800
