Types ¶
type Conn ¶
type Conn struct {
// contains filtered or unexported fields
}
Conn is a wrapper around *sql.Conn. Conn is used to track connection use time.
type ConnPool ¶
type ConnPool struct {
// contains filtered or unexported fields
}
ConnPool is a wrapper around *sql.DB. ConnPool only supports Conn() which returns a wrapped *sql.Conn. ConnPool is used to track connection wait time.
func (*ConnPool) SetConnMaxIdleTime ¶
func (*ConnPool) SetConnMaxLifetime ¶
func (*ConnPool) SetMaxIdleConns ¶
func (*ConnPool) SetMaxOpenConns ¶
type ConnPool_ ¶
type ConnPool_ interface {
