MonadicTypes.NET.Generators

Compile-time struct-callable adapters for measured MonadicTypes.NET hot paths. This is an analyzer package: it adds generated source to the consuming project and has no runtime dependency.

Requirements

C# 14 / .NET 10 consumer project
Compatible with trimming and NativeAOT
The annotated container must be a top-level, non-generic static partial class

Install

dotnet add package MonadicTypes.NET --prerelease
dotnet add package MonadicTypes.NET.Generators --prerelease

Quick Start

using MonadicTypes;

public static partial class Operations
{
    [GenerateValueFunction]
    public static long Widen(int value) => value;
}

Result<int, string> source = Result<int, string>.Ok(42);
Result<long, string> widened = source.Map(Operations.Functions.Widen);

// The original method remains callable normally.
long direct = Operations.Widen(42);

Generation Contract

The generator adds a public callable token and an aggressively inlined adapter implementing IValueFunction<TIn,TOut> or IValueAction<T>. It uses no runtime reflection, registration, or dynamic code. Async method return types work with the corresponding operators in MonadicTypes.NET.Async.

Annotatable methods must be implemented, static, non-generic, and accept exactly one by-value parameter. An optional attribute name controls the generated token name. Invalid shapes produce MTGEN001 through MTGEN004 compile-time errors.

Do not annotate every Result-related method. Cached static delegates already allocate 0 B per invocation. Generated generic callables can improve dispatch and inlining in measured hot paths, but each distinct callable can increase NativeAOT generic instantiation count and binary size.

Package	Add it for
`MonadicTypes.NET`	Result, Option, and callable contracts used by generated tokens
`MonadicTypes.NET.Async`	Async operators that accept generated tokens
