FluentHandlerValidation

A library providing extension methods to facilitate functional data handling, validation, and manipulation in C#, with a focus on robust error handling using Result types.

Overview

This library provides a set of extension methods to create fluent and expressive validation chains in C#. It integrates with Result types for improved error handling and promotes a functional programming style.

Key Features

• Chaining: Easily chain multiple validation steps using the Bind extension method.
• Error Handling: Result types make error handling explicit, preventing unhandled exceptions.
• Readability: The fluent syntax improves code readability.
• Customizable: Write your own validation functions that return Result types.

Installation (no yet)

	.Tap(_repository.SaveChanges)
	.Map(user => user.Id);
