prog.go:8: cannot convert "abcde" (type string) to type [5]uint8 直接用copy(t.f1,"abcde")也是不行的。。因为copy的第一个参数必须是slice, 方案1:利用f1[:],注意,这里f1实际上是一个fixed的array,而f1[:]是一个slice packagemainimport"fmt"typeT1struc

To convert a string into array of characters (which is slice of runes) in Go language, pass the string as argument to []rune(). This will create a slice of runes where each character is stored as an element in the resulting slice. We do not know how many characters would be there ...

string类型和[]byte类型是我们编程时最常使用到的数据结构。本文将探讨两者之间的转换方式,通过分析它们之间的内在联系来拨开迷雾。 两种转换方式 标准转换 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(...
性能分析和优化是所有软件开发人员必备的技能,也是后台大佬们口中津津乐道的话题。 Golang 作为一门“现代化”的语言,原生就包含了强大的性能分析工具pprof 和 trace。pprof 工具常用于分析资源的使用情况,可以采集程序运行时的多种不同类型的数据(例如 CPU 占用、内存消耗和协程数量等),并对数据进行分析聚合生成的...
