type ConnectionPool struct {
	*sync.Mutex
	// contains filtered or unexported fields
}

A ConnectionPool represents a standard sql.DB connection with max open > 0.

func NewConnectionPool(maxOpen, maxIdle int, dsn string, tlsConfig *tls.Config) *ConnectionPool

func (*ConnectionPool) Close 

func (c *ConnectionPool) Close()

func (*ConnectionPool) Connect 

func (c *ConnectionPool) Connect() (*sql.DB, error)

type Connector 

type Connector interface {
	Connect() (*sql.DB, error)
	Close()
}

A Connector provides a database connection. It encapsulates logic about where and how to connect, like the DSN and TLS config, so that code using a Connector does not need to know this logic. Implementations can also vary wrt connection pooling.
