Result Class Library

This library provides a set of tools for managing operation results in a robust and railway-oriented programming fashion. It offers various result types to encapsulate the outcomes of operations, handling both successes and failures gracefully without throwing exceptions. This approach enhances error handling, makes your codebase cleaner, and improves the maintainability of your applications.

Features

• Generic Result Types: Handle different data types and operations flexibly.
• Railway-Oriented Programming: Built-in methods for chaining operations based on success or failure outcomes.
• Error Handling: Advanced error handling capabilities without relying on exceptions.
• Asynchronous Support: Asynchronous methods to handle I/O-bound and CPU-intensive operations efficiently.

Installation

To install the Result Class Library, use the following NuGet command:

dotnet add package DropBear.Codex.Core

Usage Examples

Below are some examples of how to use the various result types provided by the library:

Using Result

var result = Result.Success();
if (result.IsSuccess)
{
    Console.WriteLine("Operation succeeded.");
}

var failureResult = Result.Failure("Error occurred.");
failureResult.OnFailure(error => Console.WriteLine(error));

Using Result<T>

var result = Result.Success(123);
var nextResult = result.Bind(value => Result.Success(value.ToString()));
nextResult.OnSuccess(value => Console.WriteLine($"Processed value: {value}"));

Using Result<TSuccess, TFailure>

var result = Result.Success<int, string>(42);
result.Match(
    success => Console.WriteLine($"Success with value: {success}"),
    failure => Console.WriteLine($"Failed with error: {failure}")
);

Using Result<TSuccess, TFailure> with Additional Handlers

var result = Result.Success<int, string>(42);
result.Match(
    success => Console.WriteLine($"Success with value: {success}"),
    failure => Console.WriteLine($"Failed with error: {failure}"),
    onPending: () => Console.WriteLine("Operation is pending."),
    onCancelled: () => Console.WriteLine("Operation was cancelled."),
    onWarning: () => Console.WriteLine("Operation completed with warnings."),
    onPartialSuccess: () => Console.WriteLine("Operation partially succeeded."),
    onNoOp: () => Console.WriteLine("No operation was performed.")
);

Using ResultWithPayload<T>

var data = new { Name = "Example", Value = 42 };
var result = Result.SuccessWithPayload(data);
var deserialized = result.DecompressAndDeserialize();
if (deserialized.IsSuccess)
{
    Console.WriteLine($"Data: {deserialized.Value.Name}");
}
