golang如何trunk一个map

Question

golang如何实现一个像php的array_trunk()的方法来chunk一个map?

Answer 1

func (d *scanner)ChunksAsCPUNumber()  {
    var divided [][]string
    counts := d.Count()
    CPUNum := runtime.NumCPU()
    size := (counts + CPUNum - 1) / CPUNum

    for i := 0; i < counts; i += size {
        end := i + size

        if end > counts {
            end = counts
        }

        divided = append(divided, d.Files[i:end])
    }

    fmt.Printf("%#v\n", divided)
}
