Usage:

import dhx.Try;
import dhx.Try.Macro.Try;   // macro magic
using dhx.Tries;        // useful extensions
...
var tried:Try<Int> = Try(someUnsafeOperation(foo, bar));
tried.LogFailure(); // trace exception or set define `debug_try`
var value = tried.getOrElse(function () return 0);

Global Import

import.hx

import dhx.Try;
import dhx.Try.Macro.Try;
using dhx.Tries;

Void

Try<Void> is not supported, instead of Void use thx.Nil type from thx.core haxe library.

var tried = Try(voidMethod()); // Try.Success(thx.Nil.nil);

Debug

• define debug_try - turn on exceptions log
