Rop.Results9 1.2.1

Rop.Results9

Rop.Result is a C# library that provides a way to handle errors without exceptions. Instead of throwing an exception, functions return a Result object that can be either a Success or a Failed state.

Installation

To install the library, you can use the NuGet package manager. In the Visual Studio terminal, run the following command:

Install-Package Rop.Results9

Usage

To use the library, you need to import the Rop.Result9 namespace:

using Rop.Result9;

Then you can create Result objects using implicit conversions:

public Result<int> Divide1(int dividend, int divisor)
    {
        if (divisor == 0)
        {
            return Error.Fail("Cannot divide by zero.");
        }
        else
        {
            return dividend / divisor;
        }
    }

You can also use the Result object in a fluent way:

public VoidResult ShowDivide(int divident,int divisor)
    {
        var result = Divide1(divident, divisor);
        return result.Map(
            v => Console.WriteLine($"The result is {result.Value}"),
            e => Console.WriteLine($"Error: {result.Error!.Value}")
        );
    }

public VoidResult ShowDivide2(int divident,int divisor)
    {
        var result = Divide1(divident, divisor);
        if (result.IsFailed) 
            return result;
        Console.WriteLine($"The result is {result.Value!}");
        return VoidResult.Ok;
    }
