问static_assert依赖于非类型模板参数( gcc和clang的不同行为)EN模板模式是常用的一种行为型设计模式,主要思想是在模板中定义一套流程骨架代码,并且不实现骨架代码中使用的一些方法,这些方法留给子类去实现。假如我们业务开发中有一个场景,我们的业务系统需要从不同征信渠道查询征信报告,每家机构输出的内容不一样,但是都分为3个步骤,建立连接、获取报告原...

I've got a project that uses nanopb protos to communicate via UART to another device. It looks like every proto I've defined that's not just an empty message throws a compiler error. The error is static_assert expression is not an integr...
