切片的概念在python中也存在这个概念,在go中,切片是对数组的一个连续片段的引用,所以切片是一个引用类型,它的内部结构包含地址、长度和容量。 版本号:go version go1.20 darwin/arm64 runtime/slice.go typeslicestruct{ array unsafe.Pointer lenint capint } 其中: array是底层数组指针,指向该切片的第一个元素...

Go 1.21开始成为标准包的一部分,用于比较有序数据。和slices/maps一样(也都是1.21引入,有点像stl里面的算法库),他们底层都用泛型和约束。 关键点总结 双泛型参数:可以分别指定元素类型和切片类型,提供更大的灵活性 类型安全:Go 编译器会确保类型约束得到满足 ...

A map is a inbuilt data type in Go which is used to store key-value pairs. A practical use of a map is for storing the currency codes and the corresponding currency names
