A memory pool manager implemented with generics.

Installation

Quickstart

Memory pools must be registered before they can be used. Type parameters of pool id type and pooled object type should be provided when registering.

package main

import (
	"fmt"

	"github.com/YoungerLee/gopools"
)

type PoolId uint64

type Student struct {
	ID     uint64  `json:"id"`
	Name   string  `json:"name"`
	Age    int     `json:"age"`
	Gender int     `json:"genger"`
	Class  int32   `json:"class"`
	Marks  []int32 `json:"marks"`
}

const STUDENT_POOL_ID PoolId = 1

func init() {
	gopools.Register[PoolId, Student](STUDENT_POOL_ID)
}

func main() {
	s := gopools.Get[PoolId, Student](STUDENT_POOL_ID)
	s.ID = 123456
	s.Name = "Anonymous"
	s.Age = 22
	s.Gender = 1
	s.Class = 10
	s.Marks = []int32{95, 96, 97, 8, 99, 100}
	fmt.Printf("%p|%+v", s, s)
	gopools.Put(STUDENT_POOL_ID, s)
}
