for { // infinite loop if condition { break // exit the loop } } for i < 0 { // loop with condition if condition { continue // skip current iteration and execute next } } for i:=0; i < 10; i++ { // loop with declaration, condition and operation } 当switch和for的组合嵌套...
If an old package and a new package have the same import path, the new package must be backwards compatible with the old package. 试想下如果所有我们依赖的包,一直都是接口兼容的,那就没有啥问题,也没有 DLL Hell。可惜现实却不是这样,如果我们提供过包就知道,对于持续维护和更新的包,在最初不可能...
Go 1.21在工具链方面最值得关注的就是Go团队对向后兼容(backwards compatibility)和向前兼容(forwards compatibility)的重新思考和新措施。 所谓向后兼容就是用新版Go编译器可以编译遗留的历史Go代码,并可以正常运行。比如用Go 1.21版本编译器编译基于Go 1.5版本编写的Go代码。Go在这方面做的一直很好,并提出了Go1兼容性...
Embeding 在 UTest 的 Mocking 中可以显著减少需要 Mock 的函数,比如Mocking net.Conn,如果只需要 mock Read 和 Write 两个函数,就可以通过内嵌 net.Conn 来实现,这样 loopBack 也实现了整个 net.Conn 接口,不必每个接口全部写一遍: typeloopBackstruct{ net.Conn buf bytes.Buffer }func(c *loopBack)Read(b...
先看一个典型的问题Is it possible to call overridden method from parent struct in golang?代码如下所示: packagemainimport("fmt")typeAstruct{ }func(a *A)Foo() { fmt.Println("A.Foo()") }func(a *A)Bar() { a.Foo() }typeBstruct{ ...
even when compiling with a new toolchain. People only need to debug loop changes when they opt in to the new semantics ingo.mod. This approach is in keeping with our backwards and forwards compatibility work,#56986and#57001, specifically the principle that toolchain upgrades preserve the behavio...
