You certainly can implement such a thing. The source to the bytes Index function is in the bytes_platform.go files, as it is optimized per platform: https://golang.org/src/bytes/bytes_amd64.go is the amd64 one, for example. Looking at it is a good way to see how such a thing is implemented.
A naive implementation would be something like this: https://play.golang.org/p/75H1DSWryQ But actually looking at the rest of the bytes implementation will give some insight into more efficient ways to do it On Tuesday, November 14, 2017 at 9:21:35 AM UTC-6, Christian LeMoussel wrote: > > bytes package implements Index <https://golang.org/pkg/bytes/#Index> function > (func Index(s, sep []byte) int) that returns the index of the first > instance of sep in s, or -1 if sep is not present in s. > Do you think it's possible to do the same thing with uint32 slice (func > Index(s, sep []uint32) int)? > > eg: https://play.golang.org/p/kSu3lqsbRH > buffer := "83f9eed5fb46f700c1caca" > searchByte := []byte{0x65, 0x65, 0x64, 0x35, 0x66, 0x62, 0x34, 0x36, > 0x66, 0x37} // eed5fb46f7 > if bytes.Index([]byte(buffer), searchByte) != -1 { > fmt.Println("OK") > } > > > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
