Toarnbeike.Results.FluentValidation

Integrate fluent result handling from Toarnbeike.Results with expressive validation logic from FluentValidation, providing seamless validation support for Result<T> using one or more IValidator<T> instances.

Features

  • Extension methods to validate Result<T> with one or more FluentValidation validators.
  • Support for both synchronous and asynchronous validation (Validate / ValidateAsync).
  • Automatic conversion of FluentValidation's ValidationFailure to Toarnbeike.Results.Failures.ValidationFailure.
  • Useful for pipeline-based validation or standalone use in service or domain layers.

Getting started

dotnet add package Toarnbeike.Results.FluentValidation

This package targets .NET 9+ and depends on:

  • Toarnbeike.Results
  • FluentValidation

Usage

Validate the value of a Result<TValue> if the result is successful.

var result = Result.Success(new RegisterUserCommand("John", "john@email.com"));

// Validate using one or more FluentValidation validators
var validated = result.Validate(new RegisterUserCommandValidator());

Validate asynchronously

var result = Result.Success(new RegisterUserCommand("John", "john@email.com"));

var validated = result.ValidateAsync(new RegisterUserCommandValidator());

Validate using multiple validators (coming from DI)

public class CreateUserCommandHandler(IEnumerable<IValidator<CreateUserCommand>> validators) 
{
    public async Task<Result> Handle(CreateUserCommand command)
    {
        return await Result.Success(command)
            .ValidateAsync(validators);
            // other extensions methods that handle the command.
    }
}

When to use Validate vs. ValidateAsync

Use:

  • .Validate() when your validators are fully synchronous
  • .ValidateAsync() when any of your validators use asynchronous logic, such as MustAsync, or if you are not sure.

There is currently no automatic way to detect whether an IValidator<T> from FluentValidation uses async logic; when choosing the async method the full validation is always performed, even when the IValidator<T> does not contain async logic.
