DropBear.Codex.Core

Core library providing Result pattern, functional extensions, and telemetry infrastructure for .NET 9+ applications.

🚀 Quick Start

Installation

dotnet add package DropBear.Codex.Core

Basic Usage

using DropBear.Codex.Core.Results;
using DropBear.Codex.Core.Results.Errors;

// Create a result-returning method
public Result<int, ValidationError> Divide(int numerator, int denominator)
{
    if (denominator == 0)
    {
        return Result<int, ValidationError>.Failure(
            new ValidationError("Cannot divide by zero"));
    }
    
    return Result<int, ValidationError>.Success(numerator / denominator);
}

// Use pattern matching
var result = Divide(10, 2);
var message = result.Match(
    success: value => $"Result: {value}",
    failure: error => $"Error: {error.Message}"
);

// Chain operations
var doubled = result.Map(x => x * 2);
var combined = result.Bind(x => Divide(x, 3));

✨ Features

Result Pattern

Type-safe error handling without exceptions:

Result<User, ValidationError> GetUser(int id)
{
    if (id <= 0)
        return Result<User, ValidationError>.Failure(
            new ValidationError("Invalid ID"));
    
    var user = _repository.Find(id);
    return user != null
        ? Result<User, ValidationError>.Success(user)
        : Result<User, ValidationError>.Failure(
            new ValidationError("User not found"));
}

Functional Extensions

Map, Bind, Match and more:

var result = await GetUserAsync(userId)
    .MapAsync(user => user.Email)
    .BindAsync(email => SendEmailAsync(email))
    .TapAsync(async () => await LogSuccessAsync())
    .OnFailureAsync(async error => await LogErrorAsync(error));

Telemetry Integration

Built-in OpenTelemetry support:

// Configure telemetry at startup
TelemetryProvider.Configure(options =>
{
    options.Mode = TelemetryMode.BackgroundChannel;
    options.ChannelCapacity = 10000;
});

// Automatic telemetry tracking
var result = Result<int, ValidationError>.Success(42);
// Telemetry automatically recorded!

Async/Await Support

First-class async operations:

public async Task<Result<Data, ErrorType>> ProcessAsync(
    CancellationToken cancellationToken = default)
{
    return await GetDataAsync(cancellationToken)
        .MapAsync(async (data, ct) => await TransformAsync(data, ct), cancellationToken)
        .BindAsync(async (data, ct) => await ValidateAsync(data, ct), cancellationToken);
}

Envelope Pattern

Message wrapping with metadata:

var envelope = new EnvelopeBuilder<MyData>()
    .WithPayload(myData)
    .AddHeader("version", "1.0")
    .AddHeader("source", "api")
    .Build();

// Serialize and deserialize
var json = await envelopeSerializer.SerializeAsync(envelope);
var restored = await envelopeSerializer.DeserializeAsync(json);
