也可以实现 map 的功能: // Map converts Iterator[A] to Iterator[B]. func Map[A, B any](it Iterator[A], mapping func(A)B) Iterator[B] { return func(yield func(B)bool) { for item := range it { if !yield(mapping(item)) { ...
go 中string与[]byte的互换,相信每一位 gopher 都能立刻想到以下的转换方式,我们将之称为标准转换。 // string to []byte s1 := "hello" b := []byte(s1) // []byte to string s2 := string(b) 强转换 通过unsafe 和 reflect 包,可以实现另外一种转换方式,我们将之称为强转换(也常常被人称作黑...
