WTFCache

It's a simple (non-fancy) LRU cache with generic interface without annoying limitations to comparable keys.

Example

package main

import (
	"fmt"

	"github.com/irr123/wtfcache"
)

func main() {
	c := wtfcache.New[string, string]().MakeWithLock(1e4)
	c.Set("k1", "v1")
	c.Set("k2", "v2")

	v1, ok := c.Get("k1")
	fmt.Printf("%q, %t", v1, ok)

	c.Del("k2")
}
