利用泛型实现的 golang 缓存装饰器

项目地址： https://github.com/ahuigo/gofnext#decorator-cases

类似于 python 的 @functools.cache

cache decorator 菲波那切数列示例:

package main
import "fmt"
import "github.com/ahuigo/gofnext"
func main() {
    var fib func(int) int
    var fibCached func(int) int
    fib = func(x int) int {
        fmt.Printf("call arg:%d\n", x)
        if x <= 1 {
            return x
        } else {
            return fibCached(x-1) + fibCached(x-2)
        }
    }

    fibCached = gofnext.CacheFn1(fib)    

    fmt.Println(fibCached(5))
    fmt.Println(fibCached(6))
}
