MonadicTypes.NET.Effects

Explicit exception-to-error boundaries and throwing-operation helpers for MonadicTypes.NET. This package includes MonadicTypes.NET transitively.

Requirements

  • .NET 10 or later
  • Compatible with trimming and NativeAOT

Install

dotnet add package MonadicTypes.NET.Effects --prerelease

Quick Start

using MonadicTypes;
using MonadicTypes.Effects;

Result<string, string> text = Effect.Try(
    static () => File.ReadAllText("settings.json"),
    static exception => $"Read failed: {exception.Message}");

Result<int, string> length = text.TryMap(
    static value => value.Length,
    static exception => $"Mapping failed: {exception.Message}");

Boundary Rules

  • Effect.Try, TryAsync, and TryTaskAsync start a Result pipeline around throwing code.
  • TryMap, TryBind, and TryTap protect one stage in an existing pipeline.
  • Broad overloads exclude cancellation and process-corrupting/runtime failures.
  • Typed overloads convert only the selected exception type; other exceptions propagate normally.
  • The caller owns exception-to-domain-error mapping.

Catch exceptions at narrow dependency boundaries, then return to ordinary Result composition. Do not wrap an entire application or hide programmer bugs inside a generic unexpected error.

Caller-state overloads avoid closure allocation. Completed async paths avoid an adapter Task allocation, but this package cannot remove allocations made by the underlying dependency.

Package Add it for
MonadicTypes.NET.Errors Structured errors that retain exception causes
MonadicTypes.NET.Async Continuing the resulting async pipeline
