Types

type RecursiveMutex

type RecursiveMutex struct {
	sync.Mutex // 嵌入Mutex以提供基础互斥功能
	// contains filtered or unexported fields
}

RecursiveMutex 包装一个Mutex，实现可重入

func (*RecursiveMutex) Lock

func (m *RecursiveMutex) Lock()

Lock 获取锁，支持同goroutine多次获取（重入）

func (*RecursiveMutex) Unlock

func (m *RecursiveMutex) Unlock()

Unlock 释放锁，只有当递归计数归零时才真正释放
