Unio.Extensions

Functional and fluent extensions for Unio<T0, T1> with allocation-conscious APIs and ValueTask-based async composition.

Features

  • Branch mapping: MapT0, MapT1, BindT0, BindT1
  • Async branch mapping: BindT0Async, BindT1Async (ValueTask)
  • Side-effects: TapT0, TapT1, TapT0Async, TapT1Async
  • Recovery: RecoverT0, RecoverT1
  • Validation guards: EnsureT0, EnsureT1
  • Folding: Fold, FoldAsync (ValueTask)
  • Branch observation: OnT0, OnT1
  • TryPick helpers: PickT0Or, PickT1Or
  • Dual mapping: BiMap
  • LINQ support: Select, SelectMany
  • Result bridges: ToResult, FromResult

Quick Start

using Unio;
using Unio.Extensions;

Unio<int, string> value = "invalid";

int normalized = value
    .TapT1(static error => Console.WriteLine(error))
    .EnsureT1(static e => e.Length < 20, static _ => -1)
    .RecoverT1(static _ => -1);

ValueTask Async Pipeline

using Unio;
using Unio.Extensions;

Unio<int, string> value = 21;

Unio<double, string> result = await value
    .BindT0Async(static i => ValueTask.FromResult(i * 2.0))
    .TapT0Async(static d =>
    {
        Console.WriteLine($"computed: {d}");
        return ValueTask.CompletedTask;
    });

LINQ Query Syntax

using Unio;
using Unio.Extensions;

Unio<int, string> left = 4;

Unio<int, string> sum =
    from x in left
    from y in (Unio<int, string>)(x * 3)
    select x + y;

Result Bridge

using Unio;
using Unio.Extensions;
using Unio.Types;

Unio<int, string> value = 42;

Unio<Result<int>, Error<string>> wrapped = value.ToResult();
Unio<int, string> roundtrip = wrapped.FromResult();
