std.string.format throws runtime exception for BigInt and for BitArray types
even though writefln works fine. The run-time error says
std.format.FormatException@std/format.d(4744): Can't convert std.bigint.BigInt
to string: "string toString()" not defined
Here is a small test case:
void main()
{
import std.stdio;
import std.string;
import std.bigint;
import std.bitmanip;
BigInt aa = 100;
BitArray bb;
bb.init([true, false]);
writefln("%x", aa);
writefln("%x", bb);
writeln(format("%x", aa)); // throws exception
writeln(format("%x", bb)); // throws exception
}
