Maleron.Results

Result Pattern and Railway Oriented Programming for .NET. Represents the outcome of an operation as a type instead of throwing exceptions.

Installation

dotnet add package Maleron.Results

Quick Start

using Maleron.Results;

// Create a success result
var ok = Result.Ok("Operation completed");

// Create a failure result
var fail = Result.Fail("Something went wrong");

// Check the outcome
if (ok.IsSuccess)
    Console.WriteLine(ok.Successes[0].Message);

Generic Result

Use Result<T> to carry a value on success:

Result<User> result = Result<User>.Ok("User found", user);

if (result.IsSuccess)
{
    User data = result.Data;
    Console.WriteLine($"Found: {data.Name}");
}
else
{
    Console.WriteLine($"Error: {result.Failures[0].Message}");
}

Creating Results

// Success with message
var ok = Result.Ok("Saved successfully");

// Failure with message
var fail = Result.Fail("Validation failed");

// Success with data
var withData = Result<User>.Ok("User found", user);

// Neutral result (for accumulation)
var result = Result.Create()
    .WithSuccess(new Success("Step 1 passed"))
    .WithSuccess(new Success("Step 2 passed"))
    .WithFailure(new Failure("Step 3 failed"));

API

Result

Method Description
Result.Create() Creates a neutral result
Result.Ok(string message) Creates a success result
Result.Fail(string message) Creates a failure result
Result.Fail(Failure failure) Creates a failure result from a Failure object

Result<T>

Method Description
Result<T>.Create(T? data) Creates a neutral result with optional data
Result<T>.Ok(string message, T? data) Creates a success result with optional data
Result<T>.Fail(string message, T? data) Creates a failure result with optional data

ResultBase (base class)

Property Type Description
IsSuccess bool True when no failures
IsFailure bool True when any failure exists
Reasons IReadOnlyList<IReason> All reasons (successes + failures)
Successes IReadOnlyList<Success> Only success reasons
Failures IReadOnlyList<Failure> Only failure reasons
