Types

type Config

type Config 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)
	//关闭连接的方法
	Close func(interface{}) error
	//检查连接是否有效的方法
	Ping func(interface{}) error
	//连接最大空闲时间，超过该事件则将失效
	IdleTimeout time.Duration
}

Config 连接池相关配置

type Pool

type Pool interface {
	Get() (interface{}, error)

	Put(interface{}) error

	Close(interface{}) error

	Release()

	Len() int
}

Pool 基本方法
