GO SplitAfterN用法及代碼示例

GO語言"bytes"包中"SplitAfterN"函數的用法及代碼示例。

用法:

func SplitAfterN(s, sep []byte, n int) [][]byte

SplitAfterN 在 sep 的每個實例之後將 s 切片為子切片，並返回這些子切片的切片。如果 sep 為空，則 SplitAfterN 在每個 UTF-8 序列之後拆分。計數確定要返回的子切片數：

n > 0: at most n subslices; the last subslice will be the unsplit remainder.
n == 0: the result is nil (zero subslices)
n < 0: all subslices

package main

import (
    "bytes"
    "fmt"
)

func main() {
    fmt.Printf("%q\n", bytes.SplitAfterN([]byte("a,b,c"), []byte(","), 2))
}

["a," "b,c"]
