Worked. Thanks.

import std.stdio;
import std.conv: to;
import std.exception: ifThrown;

void main( string[] args ){
        
        string str = "string";
	int index = to!int( str ).ifThrown( 0 ); // if an exception was 
thrown, it is ignored and then return ( 0 );
        writeln( "index: ", index );  // 0
}
