consider the follwoing:
import tango.io.Stdout, tango.io.Path, tango.text.Util;
import std.algorithm, std.string , std.stdio, std.array,
std.conv, std.regex, std.typecons;
//i know al imports are not necessary for this example, just ^c^v
from my actual code
alias string[] surSegments
void makeHashmap(T,R)(T[] plainArr, string hashes, out R[]
hashMap)
{
//first split the hashes
string [] hashesArr = std.algorithm.splitter(hashes, ',').array;
for(int i = 0; i < plainArr.length; i++)
{
R hashElement;
for(int j = 0; j < hashesArr.length; j++)
{
hashElement[hashesArr[j]] = = plainArr[i][j];
}
hashMap ~= hashElement;
}
}
void main()
{
surSegments[] s = [[a,b,c,d], [e,f,g,h]];
h = "1,2,3,4";
surSegments[string][] ss;
makeHashmap(s, h, ss);
}
i expect ss to look like :
[
[1 => a, 2 => b, 3 => c, 4 => d],
[1 => e, 2 => f, 3 => g, 4 => h]
]
etc.
instead i get compilation error:
Error: cannot implicitly convert expression
(hashesArr[cast(ulong)j]) of type string to string[]
isn't hashElement of type surSegment[string] and
hashElement[somestring] of type string, just like plainArr[i][j]
??
