Example

PopValidation provides a class "AbstractValidator", that you can inherit which provides the functions "Describe" and "DescribeEnumerable", which form the basis for all of the valiations, allowing you to select a field and describe the validations for that field.

An example

using PopValidation;

public record Song(string? Title, double Duration);

public class SongValidator: AbstractValidator<Song> 
{
    public SongValidator() 
    {
        RuleFor(x => x.Title).Vitally().NotEmpty();
        RuleFor(x => x.Duration)
            .IsNotNull()
            .IsLessThan(10.0, options => options.WithErrorMessage("Songs must be less than 10 minutes long."));
    }
}

// Instantiate the Validation Runner.
var runner = new ValidationRunner<Song>(
    new () { new SongValidator() },
    new MessageProcessor()
);

// Run the Validation System.
var results = await runner.Validate(new Song("A Song", 5.5));

// Determine failures;
var isFailure = results.Errors.Any();
