func NewChannelPool

func NewChannelPool(poolConfig *PoolConfig) (Pool, error)

NewChannelPool 初始化链接

type PoolConfig

type PoolConfig struct {
	//连接池中拥有的最小连接数
	InitialCap int
	//连接池中拥有的最大的连接数
	MaxCap int
	//生成连接的方法
	Factory func() (interface{}, error)
	//关闭链接的方法
	Close func(interface{}) error
	//链接最大空闲时间，超过该事件则将失效
	IdleTimeout time.Duration
}
