Lachstec.Result

Lightweight, zero-dependency library for safe and exception-free error-handling in C#. Heavily inspired by functional programming paradigms and Rust's Result type.

Table of Contents

Features

  • Strongly typed Result<TValue, TError> for operations that can succeed or fail, returning possibly different types of values.
  • Result<TError> for operations that can succeed or fail, but have no meaningful value in case of a success.
  • Combinators in a Fluent API style for chaining operations and performing control flow with results.
  • Zero dependencies, no external libraries required.

Installation

The library is published on NuGet. You can add it to your project using the following command:

dotnet add package Lachstec.Result

Usage

// Creating a result by calling a method that could fail, indicated by a result as return type
Result<int, string> result = DoSomething();

// Pattern-match on the returned result
int value = result.Match(
ok => ok * 2,
error => {
Console.WriteLine($"Error: {error}");
return -1;
});

Why use a Result type?

Many methods are designed to return a value or throw an exception. This can lead to bugs if the caller forgets to handle the exception. By using a Result type, you can ensure that the caller must handle both success and failure cases explicitly, thus ensuring that all possible cases get addressed. This Package helps you by providing a simple Result type with convenience functions to easily manipulate results and chain operations together.

Why another Result Library?

There are already a lot of libraries that provide the Result Pattern for C#, but most of them are complex and provide more than what is necessary. This library is designed to be simple and lightweight, with no dependencies, but still powerful enough to allow for ergonomic error handling.
