eQuantic.Core.Outcomes

A modern, type-safe Result Pattern for .NET with Railway-Oriented Programming: handle success and failure elegantly, without exceptions — immutable results, typed errors with severity/categorization, combinators, full async support and built-in observability (correlation IDs, execution timing).

using eQuantic.Core.Outcomes;
using eQuantic.Core.Outcomes.Errors;
using eQuantic.Core.Outcomes.Extensions;

Result<User> result = GetUser(id)                 // Result<User>.Success(user) / .Failure(error)
    .Ensure(user => user.IsActive, new Error("user.inactive", "User is inactive"))
    .Bind(user => LoadProfile(user))              // Result-returning step
    .Map(profile => profile.DisplayName)          // plain transformation
    .Tap(name => logger.LogInformation("Loaded {Name}", name));

var response = result.Match(
    onSuccess: name => $"Hello {name}",
    onFailure: errors => $"Failed: {errors[0].Message}");

// Async pipelines: MapAsync / BindAsync / TapAsync mirror the whole surface.
  • Dependency-free core — no ASP.NET Core reference; usable in any app model (console, workers, libraries).
  • Typed errors (Error, ValidationError) with ErrorType/ErrorSeverity driving HTTP mapping downstream.
  • Result shapes: BasicResult, ItemResult<T>, ListResult<T>, PagedListResult<T> with fluent builders and System.Text.Json-friendly serialization.
  • Combinators to aggregate multiple results; async variants throughout.
