Get KeyLock

You can download KeyLock to your project with the following command.

go get github.com/lyonnee/keylock

Usage

Here is a simple example of how to use KeyLock.

package main

import (
	"fmt"
	"sync"
	"time"

	"github.com/lyonnee/keylock"
)

func main() {
    // Create a KeyLocker with a length of 512.
	keylocker := keylock.NewKeyLock(512)

    key := "myKey"

    // Use KeyLocker's Lock method to get the ReadWriteLock corresponding to the key and lock it
	m := keylocker.Lock(key)

    // Example: perform some operations
    fmt.Println("do something...")
    time.Sleep(time.Second)

    // Use Unlock method to release the ReadWriteLock corresponding to the key
	m.Unlock()
}

In the above code, we first create a new KeyLocker instance (storing 512 ReadWriteLocks) via keylocker.NewKeyLock(512), then we take out a ReadWriteLock associated with the specified key and lock it via keylocker.Lock(key). After performing necessary operations, we unlock the ReadWriteLock via the m.Unlock() method.

At the same time, KeyLocker uses the global lock sync.Mutex to ensure concurrency safety, and it uses hash to manage keys. In this way, the ReadWriteLocks corresponding to different keys will not affect each other, making it suitable for scenarios where concurrent processing of multiple tasks is required.
