如何从地图转换MapResult!一组整数？

Question

我需要的方式来隐式地转换MapResult map!模板从类型auto到int [].我该怎么做？

import std.stdio;
import std.conv;
import std.array;
import std.algorithm;

void main()
{
    string s = "1,3,5,6,8";

    int x [];
    // auto xx = s.split(",").map!(a => to!int(a)); // working code
     x = s.split(",").map!(a => to!int(a)); // not working
    writeln(x);
}

Answer 1

隐式不可能,但明确地array:

int[] x = s.split(",").map!(a => a.to!int).array;
