typeHashinterface{// Write (via the embedded io.Writer interface) adds more data to the running hash.// It never returns an error.io.Writer// Sum appends the current hash to b and returns the resulting slice.// It does not change the underlying hash state.Sum(b []byte) []byte// Re...
上面那个例子是有方法的interface作为参数,但是很多时候还会出现一种空interface 空interface(interface{})不包含任何的method,因此所有的类型都实现了空interface。 https://tiancaiamao.gitbooks.io/go-internals/content/zh/07.2.htmlinterface 原理 因此空Interface就很像C语言里面的空指针。 comma-ok 但是不同的是,...

interface{}// Nothing是一个定义空接口类型。typeNothinginterface{} 事实上,Go 1.18引入了一个预声明的类型别名any,用来表示空接口类型interface{}。 一个空接口类型的类型集由所有由非接口类型组成。 2 类型实现(implementation) 如果一个非接口类型处于一个接口类型的类型集中,则我们说此非接口类型实现了此接口类...
default: // 不知道i是什么类型,因此j的类型为interface{} } } 类型判断和switch语句很像,我们在代码块,遮蔽和控制结构一章中学习过。取代指定布尔运算,我们指定一个接口类型的变量在其后接.(type)。通常将待检测变量赋给另一个仅在switch中有效的变量。
