Trellis.Core

NuGet Package

Railway-oriented error handling and domain foundations for .NET with Result<T>, Maybe<T>, typed errors, value-object bases, and DDD primitives.

Installation

dotnet add package Trellis.Core

Quick Example

using Trellis;

Result<string> email = Result.Ok("ada@example.com")
    .Ensure(
        value => value.Contains('@'),
        Error.InvalidInput.ForField(
            "email",
            ValidationCodes.StringEmail,
            "Email is invalid."))
    .Map(value => value.Trim().ToLowerInvariant());

Key Features

  • Compose explicit success and failure paths with Bind, Map, Tap, Ensure, Combine, and their async variants.
  • Use static Result.Ensure(condition, () => error) guards to create errors only on failure; predicate and async-predicate overloads support the same lazy factories.
  • Model expected absence with Maybe<T> instead of null or exceptions.
  • Treat blank optional text as absent with Maybe.OptionalNonBlank; nonblank input reaches the factory unchanged, while Maybe.Optional remains null-only.
  • Return a closed set of typed errors that adapters can map consistently.
  • Accumulate failures with EnsureAll, including lazy value-dependent error factories.
  • Compose nested validation paths with InputPointer.AppendProperty and AppendIndex, preserving location and RFC 6901 escaping.
  • Build aggregates, entities, value objects, specifications, domain events, and integration-event contracts.
  • Define source-generated Required*<TSelf> scalar value objects.
  • Validate cursor pagination with PageRequest, CursorCodec, Page<T>, and PageBuilder.
  • Classify failures for retry-aware workers and consumers.

Result<T> is deliberately not directly JSON-serializable. At an HTTP boundary, map it with Trellis.Asp.ToHttpResponse(); elsewhere, unwrap it through Match or TryGetValue before serialization.

Generated Required*<TSelf> types are lenient by default: use [NotDefault] to reject sentinel values and [Trim] to normalize strings.

Package Downloads
Trellis.Authorization

Lightweight authorization primitives for Trellis. Provides Actor, IActorProvider, IAuthorize, IAuthorizeResource of TResource, IResourceLoader, and ResourceLoaderById types that integrate with the Trellis Result type system. No dependency on any mediator or web framework.
Trellis.Primitives

Infrastructure and ready-to-use implementations for primitive value objects in Domain-Driven Design. Includes base classes (RequiredString, RequiredGuid) with source generation, plus EmailAddress with RFC 5322 validation. Eliminates primitive obsession with strongly-typed domain primitives.
Trellis.Asp

ASP.NET Core integration for Trellis. Result-to-HTTP response mapping, rate-limit rejection handling, scalar value validation, JSON converters (with bundled AOT source generator), and ASP.NET actor providers (Claims, Entra, Easy Auth, Development) for Trellis.Authorization.
Trellis.Mediator

Result-aware pipeline behaviors for martinothamar/Mediator. Provides validation, authorization, logging, tracing, and exception handling behaviors that understand Trellis Result types and short-circuit correctly.
Trellis.Testing

FluentAssertions extensions and test doubles for Trellis - assert Result, Maybe, and Error types with readable fluent syntax
